(1) Only available in tape and reel packaging. A reel
contains 2500 devices.
(2) Lead free product. This product is fully WEEE and
RoHS compliant.
Chip supply voltage
Logic high indicates correct output voltage
Over voltage protection.
Sets the converter overcurrent trip point
Input from the phase node between the MOSFET’S
High side driver output
Power ground
Low side driver output
Bootstrap, low side driver.
Bootstrap, high side driver.
Voltage sense input
Buffered band gap voltage reference.
Soft start. A capacitor to ground sets the slow start time.
Signal ground
