TOREX XC6408 User Manual

XC6408 Series

ETR0331-005

28V Operation Voltage Regulator with Voltage Detector

■GENERAL DESCRIPTION

The XC6408 series is a positive voltage regulator IC manufactured using CMOS process with 28V operation voltage. The series consists of a voltage reference, an error amplifier, a current limiter, a thermal shutdown circuit and a phase compensation circuit plus a driver transistor. The output voltage and the detect voltage are user selectable in 0.1V increments. The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature limit level. The XC6408D series monitors its output voltage and provides reset signal if its output voltage falls below the pre-set voltage. This reset time (release delay time) can be set by an external capacitor. The XC6408E series monitors an external power supply and enables the output to be turned off and the IC becomes a stand-by mode.

■ OPERATIONAL EXPLANATION

XC6408 D Series

<Voltage Regulator> The voltage divided by resistors R11 & R12 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET which is connected to the V at the V and thermal protection circuit operate in relation to the level of output current and heat generation. For the XC6408E, regulator operation returns active state when V is higher than VD detect voltage + hysteresis width).

<Limit Current, Short-Circuit Protection> The XC6408 series includes a current fold-back circuit as a short circuit protection. When the load current reaches the current limit, the current fold-back circuit starts to operate. As a result, the output voltage drops further and output current decreases. When the V

<Thermal Protection> When the junction temperature of the built-in driver transistor reaches the temperature limit, the thermal shutdown circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is released and the IC’s operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release voltage.

<Minimum Operating Voltage> For the stable operation of the IC, over 2.0V of input voltage is necessary. The output voltage may not be generated

■ NOTES ON USE

1． Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising

phenomenon, the IC is liable to malfunction should the ratings be exceeded.

2． The power input pin voltage will falls down because of a resistance between power supply and power input pin and shoot

through current when IC operates. At this time, if the power input pin voltage is lower than operating voltage range, the IC

may cause device malfunction.

3. Please note if the power input pin voltage will fluctuated, the IC may cause device malfunction.

4. If assumed the power input pin voltage falls suddenly (e.g. falls from 28.0V to 0V) at release operation when VD delay capacitor pin is connected to a capacitor, please connect a schottky barrier diode between the power input pin and delay capacitance pin. Please refer below; (XC6408D).

5. The V

the output pin.

* When the pull-up resistor connects to another power supply, high level value will be equal to the voltage which the pull-up

resistor is connected.

6. If the input voltage fluctuates more than 1.5V in the speed higher than 100mV/μs, the output voltage may fluctuate widely.

In this case, one capacitor should be added between VIN-VSS to adjust the input fluctuation speed less than 100mV/μs.

7. For a delay capacitor pin of the XC6408D is designed in high impedance. When this pin is left open for use, the IC may get noise. It is recommended that a capacitor more than 3pF is connected to the delay capacitor pin.

8. Phase compensation is performed in the XC6408 inside. Therefore, an abnormal oscillation does not occur even if there is

no output capacitor C input stability. Also, the output voltage fluctuation such as under shoot or over shoot, which occurs because of the load change can be controlled by placing the output capacitor C The input capacitor (C
