IRF7821 Power MOSFET

IRF7821 Description

PD - 94579B IRF7821 HEXFET® Power MOSFET Applications l High Frequency Point-of-Load Synchronous Buck Converter for Applications in Networking & Comp.

IRF7821 Features

* Cdv/dt turn on. The drain of Q2 is connected to the switching node of the converter and therefore sees transitions between ground and Vin. As Q1 turns on and off there is a rate of change of drain voltage dV/dt which is capacitively coupled to the gate of Q2 and can induce a voltage spike on the ga
