NCP81152, Synchronous Buck Dual MOSFET Driver
Pin No.
Symbol Description 1, 5 BST1, BST2 Floating bootstrap supply pin for high *side gate driver.
Connect the bootstrap capacitor between this pin and the SW pin.
2, 6 PWM1, PWM2 Control input.
The PWM signal has three states: PWM = High enables the high *side FET; PWM = Mid e
NCP81152 Synchronous Buck Dual MOSFET Driver The NCP81152 is a high performance dual MOSFET gate driver optimized to drive the gates of both high side and low side power MOSFETs in a synchronous buck converter.
Two drivers are co packaged into a 2.5 mm x 3.5 mm QFN16 package that greatly reduces the footprint compared to two discrete drivers.
Adaptive anti cross conduction circuitry and power saving operation provides a low switching
