Pin Functions

PIN I/O(1) DESCRIPTION
NAME NO.
DRVH 9 O High-side N-channel MOSFET gate driver output. SW referenced driver switches between SW(OFF) and VBST(ON).
DRVL 7 O Low-side N-Channel MOSFET gate driver output. PGND referenced driver switches between PGND(OFF) and VREG5(ON).
EN 4 I Enable. Pull high to enable converter.
PG 2 O Open drain power good output.
PGND 6 I System ground.
SW 8 I/O Switch node connections for both the high-side driver and overcurrent comparator.
VBST 10 I High-side MOSFET gate driver bootstrap voltage input. Connect a capacitor from VBST to SW. An internal diode is connected between VREG5 and VBST
VFB 1 I D-CAP2 feedback input. Connect to output voltage with resistor divider.
VIN 5 I Supply Input for 5-V linear regulator. Bypass to GND with a minimum 0.1-μF high quality ceramic capacitor.
VREG5 3 O Output of 5-V linear regulator and supply for MOSFET driver. Bypass to GND with a minimum 4.7-μF high-quality ceramic capacitor. VREG5 is active when EN is asserted high.
(1) I = input, O = output
