Description

The FSL156MRBN is an integrated Pulse Width Modulation (PWM) controller and SenseFET specifically designed for offline Switch-Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fixed-frequency oscillator, Under-Voltage Lockout (UVLO), LeadingEdge Blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise current sources for loop compensation, and self-protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSL156MRBN series can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform suited for cost-effective design of a flyback converter.

Functional Description

1. Startup: At startup, an internal high-voltage current

source supplies the internal bias and charges the external capacitor (C illustrated in Figure 17. When V FSL156MRBN begins switching and the internal highvoltage current source is disabled. Normal switching operation continues and the power is supplied from the auxiliary transformer winding unless VCC goes below the stop voltage of 7.5V.

2. Soft-Start: The internal soft-start circuit increases

PWM comparator inverting input voltage, together with the SenseFET current, slowly after startup. The typical soft-start time is 15ms. The pulse width to the power switching device is progressively increased to establish the correct working conditions for the transformers, inductors, and capacitors. The voltage on the output capacitors is progressively increased to smoothly establish the required output voltage. This helps prevent transformer saturation and reduces stress on the secondary diode during startup.

3. Feedback Control: This device employs CurrentMode control, as shown in Figure 18. An opto-coupler (such as the FOD817) and shunt regulator (such as the KA431) are typically used to implement the feedback network. Comparing the feedback voltage with the voltage across the R

resistor makes it possible to

SENSE

control the switching duty cycle. When the reference pin voltage of the shunt regulator exceeds the internal reference voltage of 2.5V, the opto-coupler LED current increases, pulling down the feedback voltage and reducing drain current. This typically occurs when the input voltage is increased or the output load is decreased.

3.1 Pulse-by-Pulse Current Limit: Because CurrentMode control is employed, the peak current through the SenseFET is limited by the inverting input of PWM comparator (V

*), as shown in Figure 18. Assuming

FB

that the 90A current source flows only through the internal resistor (3R + R =25k), the cathode voltage of diode D2 is about 2.8V. Since D1 is blocked when the feedback voltage (V

) exceeds 2.8V, the

FB

maximum voltage of the cathode of D2 is clamped at this voltage. Therefore, the peak value of the current through the SenseFET is limited.

3.2 Leading-Edge Blanking (LEB): At the instant the internal SenseFET is turned on, a high-current spike usually occurs through the SenseFET, caused by primary-side capacitance and secondary-side rectifier reverse recovery. Excessive voltage across the R

SENSE

resistor leads to incorrect feedback operation in the Current-Mode PWM control. To counter this effect, the leading-edge blanking (LEB) circuit inhibits the PWM comparator for t

(300ns) after the SenseFET is

LEB

turned on.

4. Protection Circuits: The FSL156MRBN has several self-protective functions, such as Overload Protection (OLP), Abnormal Over-Current Protection (AOCP), Output-Short Protection (OSP), Over-Voltage Protection (OVP), and Thermal Shutdown (TSD). All the protections are implemented as auto-restart. Once the fault condition is detected, switching is terminated and the SenseFET remains off. This causes V

stop voltage of 7.5V, the protection is reset and the startup circuit charges the VCC capacitor. When VCC reaches the start voltage of 12.0V, normal operation resumes. If the fault condition is not removed, the SenseFET remains off and V

drops to stop voltage

CC

again. In this manner, the auto-restart can alternately enable and disable the switching of the power SenseFET until the fault condition is eliminated. Because these protection circuits are fully integrated into the IC without external components, reliability is improved without increasing cost.

Figure 19. Auto-Restart Protection Waveforms

4.1 Overload Protection (OLP): Overload is defined

as the load current exceeding its normal level due to an unexpected abnormal event. In this situation, the protection circuit should trigger to protect the SMPS. However, even when the SMPS is in normal operation, the overload protection circuit can be triggered during the load transition. To avoid this undesired operation, the overload protection circuit is designed to trigger only after a specified time to determine whether it is a transient situation or a true overload situation. Because of the pulse-by-pulse current-limit capability, the maximum peak current through the SenseFET is limited and, therefore, the maximum input power is restricted with a given input voltage. If the output consumes more than this maximum power, the output voltage (V

) decreases

OUT

below the set voltage. This reduces the current through the opto-coupler LED, which also reduces the opto-coupler transistor current, increasing the feedback voltage (VFB). If VFB exceeds 2.5V, D1 is blocked and the 2.0µA current source starts to charge

slowly up. In this condition, VFB continues

C

FB

increasing until it reaches 7.0V, when the switching operation is terminated, as shown in Figure 20. The delay for shutdown is the time required to charge C from 2.5V to 7.0V with 2.0µA. A 25 ~ 50ms delay is typical for most applications. This protection is implemented in Auto-Restart Mode.

Figure 20. Overload Protection

4.2 Abnormal Over-Current Protection (AOCP):

When the secondary rectifier diodes or the transformer pins are shorted, a steep current with extremely high di/dt can flow through the SenseFET during the minimum turn-on time. Even though the FSL156MRBN has overload protection, it is not enough to protect in that abnormal case due to the severe current stress imposed on the SenseFET until OLP is triggered. The internal AOCP circuit is shown in Figure 21. When the gate turn-on signal is applied to the power SenseFET, the AOCP block is enabled and monitors the current through the sensing resistor. The voltage across the resistor is compared with a preset AOCP level. If the sensing resistor voltage is greater than the AOCP level, the set signal is applied to the S-R latch, resulting in the shutdown of the SMPS.

Figure 21. Abnormal Over-Current Protection

FSL156MRBN — Green-Mode Fairchild Power Switch (FPS™)

FB

4.3. Output-Short Protection (OSP): If the output is shorted, steep current with extremely high di/dt can flow through the SenseFET during the minimum turnon time. Such a steep current brings high-voltage stress on the drain of the SenseFET when turned off. To protect the device from this abnormal condition, OSP is included. It is comprised of detecting V SenseFET turn-on time. When the V

is higher than

FB

2.0V and the SenseFET turn-on time is lower than

1.0s, this condition is recognized as an abnormal error and PWM switching shuts down until V reaches V

again. An abnormal condition output

5. Soft Burst-Mode Operation: To minimize power dissipation in Standby Mode, the FSL156MRBN enters Burst-Mode operation. As the load decreases, the feedback voltage decreases. As shown in Figure 23, the device automatically enters Burst Mode when the feedback voltage drops below V

(350mV). At this

BURL

point, switching stops and the output voltages start to drop at a rate dependent on standby current load. This causes the feedback voltage to rise. Once it passes V

(500mV), switching resumes. The feedback

BURH

voltage then falls and the process repeats. Burst Mode alternately enables and disables SenseFET switching, reducing switching loss in Standby Mode.

FSL156MRBN — Green-Mode Fairchild Power Switch (FPS™)

Figure 22. Output-Short Protection

4.4 Over-Voltage Protection (OVP): If the

secondary-side feedback circuit malfunctions or a solder defect causes an opening in the feedback path, the current through the opto-coupler transistor becomes almost zero. Then VFB climbs up in a similar manner to the overload situation, forcing the preset maximum current to be supplied to the SMPS until the overload protection is triggered. Because more energy than required is provided to the output, the output voltage may exceed the rated voltage before the overload protection is triggered, resulting in the breakdown of the devices in the secondary side. To prevent this situation, an OVP circuit is employed. In general, the V and the FSL156MRBN uses V monitoring the output voltage. If V

is proportional to the output voltage

CC

instead of directly

CC

exceeds 24.5V,

CC

an OVP circuit is triggered, resulting in the termination of the switching operation. To avoid undesired activation of OVP during normal operation, V

should

CC

be designed to be below 24.5V.

4.5 Thermal Shutdown (TSD): The SenseFET and the control IC on a die in one package makes it easier for the control IC to detect the over temperature of the SenseFET. If the temperature exceeds ~135C, the thermal shutdown is triggered and stops operation. The FSL156MRBN operates in Auto-Restart Mode until the temperature decreases to around 75C, when normal operation resumes.

Figure 23. Burst-Mode Operation

6. Random Frequency Fluctuation (RFF): Fluctuating

switching frequency of an SMPS can reduce EMI by spreading the energy over a wide frequency range. The amount of EMI reduction is directly related to the switching frequency variation, which is limited internally. The switching frequency is determined randomly by external feedback voltage and an internal free-running oscillator at every switching instant. RFF effectively scatters EMI noise around typical switching frequency (67kHz) and can reduce the cost of the input filter included to meet the EMI requirements (e.g. EN55022).

Key Design Notes

1. The delay for overload protection is designed to be about 30ms with C105 (8.2nF). OLP time between 39ms (12nF) and 46ms (15nF) is recommended.

2. The SMD-type capacitor (C106) must be placed as close as possible to the V abrupt pulsating noises and to improve ESD and surge immunity. Capacitance between 100nF and 220nF is recommended.
