NCP81253 5V MOSFET Driver Compatible

Pin No. Pin Name Description 1 BST Floating bootstrap supply pin for the high *side gate driver. Connect the external bootstrap capacitor between this pin and SW. 2 PWM Control input: PWM = High ³ DRVH is high, DRVL is low. PWM = Mid ³ DRVH and DRVL are low. PWM = Low ³ DRVH is low,.

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. A VCC .
