3 / 9 page 2-443 Functional Pin Description PVCC (Pin 1) PVCC is the power source for the npn transistor output device. PVCC is connected internally to VCC through a resistor. Bulk capacitance should be placed between this pin and PGND to minimize voltage deviations. PGND (Pin 2) PGND is power ground for the N-Channel MOSFET output device. Tie this pin to the ground plane of the circuit board. GND (Pin 3) GND is signal ground for the IC. Tie this pin to the ground plane of the circuit board. VCC (Pin 4) VCC provides bias power to the chip. It should be tied to system 5V. Provide local decoupling to this pin. CAP (Pin 5) Connect a capacitor to GND to set the internal amplifiers’ on-time response to a rapid voltage change at the SNS pin. SNS (Pin 6) SNS is the remote sense of the output voltage to be regulated. If the output voltage increases rapidly by greater than 1.5%, the lower amplifier responds by turning on the N- Channel MOSFET to sink current through the OUT pin to PGND. If the output voltage decreases rapidly by greater than 1%, the upper amplifier responds by turning on the npn transistor to source current from PVCC to OUT. OUT (Pin 7) This pin is the output pin of the IC. Tie this pin directly to the voltage to be regulated. EN/OT or EN (Pin 8) This pin is the only differentiation between the HIP6200 and the HIP6201. On the HIP6200, this pin is multiplexed. It is chip enable and also an overtemperature indicator. When this pin is low, the chip is disabled. If an overtemperature occurs, this pin will be pulled low internally. Tie EN/OT to a pull-up resistor and drive with an open collector signal. On the HIP6201, this pin is chip enable only. Pulling it low disables the IC. EN should be driven with a logic signal. HIP6200, HIP6201 |
