SC420A
High Speed, Combi-Sense , Synchronous Power MOSFET Driver for Mobile Applications
POWER MANAGEMENT Description
The SC420A is a cost effective Dual MOSFET Driver, incorporating Semtech’s patented Combi-SenseTM technology, designed for switching High and Low side Power MOSFETs Step-down Switching regulators. A 30ns max POWERin MANAGEMENT propagation delay from input transition to the gate of www.DataSheet4U.com the power FET’s guarantees operation at high switching frequencies. Internal overlap protection circuit prevents shoot-through from Vin to GND in the main and synchronous MOSFETs. reducing switching losses at high frequencies without causing thermal stress on the driver.
