NCP81253 - 5V MOSFET Driver Compatible

Pin No.

Pin Name Description 1 BST Floating bootstrap supply pin for the high *side gate driver.

Connect the external bootstrap capacitor between this pin and SW.

2 PWM Control input: PWM = High ³ DRVH is high, DRVL is low.

PWM = Mid ³ DRVH and DRVL are low.

PWM = Low ³ DRVH is low,

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.
