Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 ENABLE I Logic level input that starts or stops the controller from an external user command. A high level turns the controller on. This pin has a high-impedance internal pull-up integrated into the device. Because this pin is high impedance, a 10-nF capacitor to ground or an external pull-up resistor (100 kΩ) to VDD is recommended to avoid noise coupling to this pin.
2 FB I Inverting input to the error amplifier
3 COMP O Output of the error amplifier. Connecting a resistance from COMP to GND sets the output short circuit detection threshold. See applications information for details.
4 VDD I Power input to the controller
5 GND — Common connection for the controller
6 BP5 O Output bypass for the internal regulator. Connect 4.7-μF capacitor from this pin to GND. Low power, low noise loads may be connected here if desired. The sum of the external load and the gate drive requirements must not exceed 40 mA. The regulator is turned off when the ENABLE pin is pulled low.
7 LDRV O Output to the rectifier FET gate
8 BOOT I Power supply for the flying high-side driver
9 SW I Sense line for the adaptive anti cross conduction circuitry. Serves as common connection for the flying high side FET driver
10 HDRV O Bootstrapped output for driving the gate of the high side N channel FET.
