side gate driver.

Connect the external bootstrap capacitor between this pin and SW.

PWM = High ³ DRVH is high, DRVL is low.

Overview

NCP81253 5 V MOSFET Driver Compatible with Single-Phase IMVP8 Controllers The NCP81253 is a high performance dual MOSFET gate driver in a small 2 mm x 2 mm package, optimized to drive the gates of both high−side and low−side power MOSFETs in a synchronous buck converter.

The driver outputs can be placed into a high−impedance state via the tri−state PWM and EN inputs.

The NCP81253 comes packaged with an integrated boost diode to minimize external components.

A VCC UVLO function guarantees the outputs are low when the supply voltage is low.
