NCP81158D, Synchronous Buck MOSFET Driver
Pin No.
Symbol Description 1 BST Floating bootstrap supply pin for high side gate driver.
Connect the bootstrap capacitor between this pin and the SW pin.
2 PWM Control input.
The PWM signal has three distinctive states: Low = Low Side FET Enabled, Mid = Diode Emulation Enabled, High = Hig
DATA SHEET www.onsemi.com Synchronous Buck MOSFET Driver NCP81158D The NCP81158D is a high performance dual MOSFET gate driver in a small 3 mm x 3 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 NCP81158D comes packaged with an integrated boost diode to minimize external components.
