Pin Functions

PIN I/O(1) DESCRIPTION
NAME NO.
BST 1 I High-side N-channel FET bootstrap voltage input; power supply for high-side driver
DRVH 8 O High-side N-channel gate drive output
DRVL 5 O Synchronous low-side N-channel gate drive output
GND 6 — Synchronous low-side N-channel gate drive return and IC reference
PWM 2 I PWM input. A tri-state voltage on this pin turns OFF both the high-side (DRVH) and low-side drivers (DRVL)
SKIP 3 I When SKIP is LO, the zero crossing comparator is active; the power chain enters discontinuous conduction mode when the inductor current reaches zero. When SKIP is HI, the zero crossing comparator is disabled, and the driver outputs follow the PWM input. A tri-state voltage on SKIP puts the driver into a very-low power state.
SW 7 I/O High-side N-channel gate drive return. Also, zero-crossing sense input
Thermal Pad — Tie to system GND plane with multiple vias
VDD 4 I 5-V power supply input; decouple to GND with a ceramic capacitor with a value of 1 µF or greater
(1) I = Input, O = Output
