Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

Description

The FAN7602C is a green current-mode PWM controller. It is specially designed for off-line adapter applications; DVDP, VCR, LCD monitor applications; and auxiliary power supplies.

The internal high-voltage startup switch and the burst mode operation reduce the power loss in standby mode. As a result, the input power is lower than 1 W when the input line voltage is 265 V no-load condition, input power is under 0.15 W.

The maximum power can be limited constantly, regardless of the line voltage change, using the power limit function.

The switching frequency is not fixed and has random frequency fluctuation.

The FAN7602C includes various protections for the system reliability and the internal soft-start prevents the output voltage over-shoot at startup.

Application Information

1. Startup Circuit and Soft-Start Block

The FAN7602C contains a startup switch to reduce the power loss of the external startup circuit of the conventional PWM converters. The internal startup circuit charges the V source if the AC line is connected. The startup switch is turned off 15 ms after IC starts up, as shown in Figure

19. The soft-start function starts when the V reaches the start threshold voltage of 12 V and ends when the internal soft-start voltage reaches 1 V. The internal startup circuit starts charging the V again if the V

operating voltage, 8 V. The UVLO block shuts down the output drive circuit and some blocks to reduce the IC operating current and the internal soft-start voltage drops to zero. If the V threshold voltage, the IC starts switching again and the soft-start block works as well.

During the soft-start, pulse-width modulated (PWM) comparator compares the CS/FB pin voltage with the soft-start voltage. The soft-start voltage starts from 0.5 V and the soft-start ends when it reaches 1 V and the softstart time is 10 ms. The startup switch is turned off when the soft-start voltage reaches 1.3 V.

3. Current Sense and Feedback Block

The FAN7602C performs the current sensing for the current mode PWM and the output voltage feedback with only one pin, pin 3. To achieve the two functions with one pin, an internal Leading-Edge Blanking (LEB) circuit to filter the current sense noise is not included because the external RC filter is necessary to add the output voltage feedback information and the current sense information.

2. Oscillator Block

The oscillator frequency is set internally and FAN7602C has a random frequency fluctuation function.

Fluctuation of the switching frequency of a switched power supply can reduce EMI by spreading the energy over a wider frequency range than the bandwidth measured by the EMI test equipment. The amount of EMI reduction is directly related to the range of the frequency variation. The range of frequency variation is fixed internally; however, its selection is randomly chosen by the combination of external feedback voltage and internal free-running oscillator. This randomly chosen switching frequency effectively spreads the EMI noise nearby switching frequency and allows the use of a cost-effective inductor instead of an AC input line filter to satisfy the world-wide EMI requirements.

Figure 21. Current Sense and Feedback Circuits

Figure 22 shows typical voltage waveforms of the CS/FB pin. The current sense waveform is added to the offset voltage, as shown in the Figure 22. The CS/FB pin voltage is compared with PWM that is 1 V - Plimit offs et. If the CS/FB voltage meets PWM+, the output drive is shut off. If the feedback offset voltage is LOW, the switch on-time is increased. If the feedback offset voltage is HIGH, the switch on-time is decreased. In this way, the duty cycle is controlled according to the output load condition. Generally, the maximum output power increases as input voltage increases because the current slope during switch on-time increases.

IN

To limit the output power of the converter constantly, the power limit function is included in FAN7602C. Sensing the converter input voltage through the Latch/Plimit pin, the Plimit offset voltage is subtracted from 1 V. As shown in Figure 22, the Plimit offset voltage is subtracted from 1 V and the switch on-time decreases as the Plimit offset voltage increases. If the converter input voltage increases, the switch on-time decreases, keeping the output power constant. The offset voltage is proportional to the Latch/Plimit pin voltage and the gain is 0.16. If the Latch/Plimit voltage is 1 V, the offset voltage is 0.16 V.

5.1 Overload Protection (OLP)

The FAN7602C contains the overload protection function. If the output load is higher than the rated output current, the output voltage drops and the feedback error amplifier is saturated. The offset of the CS/FB voltage representing the feedback information is almost zero. As shown in Figure 24, the CS/FB voltage is compared with 50 mV reference when the internal clock signal is HIGH and, if the voltage is lower than 50 mV, the OLP timer starts counting. If the OLP condition persists for 22 ms, the timer generates the OLP signal. The protection is reset by the UVLO. The OLP block is enabled after the soft-start finishes.

Figure 24. Overload Protection Circuit

5.2 Line Under-Voltage Protection

If the input voltage of the converter is lower than the minimum operating voltage, the converter input current increases too much, causing components failure. Therefore, if the input voltage is LOW, the converter should be protected. The LUVP circuit senses the input voltage using the LUVP pin and, if this voltage is lower than 2 V, the LUVP signal is generated. The comparator has 0.5 V hysteresis. If the LUVP signal is generated, the output drive block is shut down, the output voltage feedback loop is saturated, and the OLP works if the

Figure 22. CS/FB Pin Voltage Waveforms

LUVP condition persists more than 22 ms.

4. Burst-Mode Block

The FAN7602C contains the burst-mode block to reduce the power loss at a light-load and no load. A hysteresis comparator senses the offset voltage of the Burst+ for the burst mode, as shown in Figure 23. The Burst+ is the sum of the CS/FB voltage and Plimit offset voltage. The FAN7602C enters the burst mode when the offset voltage of the Burst+ is higher than 0.95 V and exits the burst mode when the offset voltage is lower than 0.88 V. The offset voltage is sensed during the switch off time.

5.3 Latch Protection

The latch protection is provided to protect the system against abnormal conditions using the Latch/Plimit pin. The Latch/Plimit pin can be used for the output overvoltage protection and/or other protections. If the Latch/ Plimit pin voltage is made higher than 4 V by an external circuit, the IC is shut down. The latch protection is reset when the V
