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.
