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.
