Product Overview NCP81253: 5 V MOSFET Driver Compatible with Single-Phase IMVP8 Controllers For complete documentation, see the data sheet Product Description The NCP81253 is a high-performance dual MOSFET gate driver in a small 2 mm x 2mm 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 highimpedance state via the tri-state PWM and EN inputs. The NCP81253 comes packaged with an integrated boost diode to minimize the number of external components. A VCC UVLO function guarantees the outputs are low when the supply voltage is low.
