Dual Bootstrapped, 12 V MOSFET Driver with Output Disable

The ADP3121 is a dual, high voltage MOSFET driver optimized for driving two N−channel MOSFETs, the two switches in a non−isolated synchronous buck power converter. Each driver is capable of driving a 3000 pF load with a 20 ns propagation delay and a 15 ns transition time.

Features

• All−In−One Synchronous Buck Driver

• Bootstrapped High−Side Drive

• One PWM Signal Generates Both Drives

• Anticross Conduction Protection Circuitry

• Overvoltage Protection

• OD for Disabling the Driver Outputs

• Meets CPU VR Requirement when Used with Flex−Mode Controller

• These are Pb−Free Devices

Typical Applications

• Multiphase Desktop CPU Supplies

• Single Supply Synchronous Buck Converters
