GENERAL DESCRIPTION

The ADP3416 is a dual MOSFET driver optimized for driving

two N-channel MOSFETs which are the two switches in a

nonisolated synchronous buck power converter. One of the

drivers can be bootstrapped and is designed to handle the

REV. A

FEATURES

All-In-One Synchronous Buck Driver

Bootstrapped High Side Drive

One PWM Signal Generates Both Drives

Anticross-Conduction Protection Circuitry

Pulse-by-Pulse Disable Control

APPLICATIONS

Mobile Computing CPU Core Power Converters

Multiphase Desktop CPU Supplies

Single-Supply Synchronous Buck Converters

Standard-to-Synchronous Converter Adaptations

high voltage slew rate associated with “floating” high side

gate drivers. The ADP3416 includes overlapping drive pro-

tection (ODP) to prevent shoot-through current in the external

MOSFETs.

The ADP3416 is specified over the commercial temperature

range of 0°C to 70°C and is available in an 8-lead SOIC package.
