12V MOSFET Drivers with Output Disable

for Single Phase Synchronous-Rectified Buck Converter

Features

General Description

The uP1959 is a dual, high voltage MOSFET driver All-In-One Synchronous Buck Drivers

optimized for driving two N-channel MOSFETs in a

synchronous-rectified buck converter. Each driver is

capable of driving a 5000pF capacitive load with 30ns

transition time. This device combined with uPI multi-phase

Integrated Bootstrap Diode

Adaptive Anti-Shoot-Through Protection

Circuitry

regulator for advanced micro-processors.

Output Disable Control Turans Off both

The uP1959 features adaptive anti-shoot-through

protection that prevents cross-conduction of the external

MOSFET while maintains minimum deadtime for optimized

efficiency.

MOSFETs

Under Voltage Lockout for Supply Input

WDFN2x2 - 8L and WDFN3x3 - 8L Packages

RoHS Compliant and Halogen Free

This part has integrated bootstrap diode to help minimize

the external component count. Both gate drives are turned

off by pulling low OD# pin or high-impedance at PWM

pin, preventing rapid output capacitor discharge during

system shutdown.

Applications

Desktop CPU Core Voltage Regulators

High Frequency Low Profile DC/DC Converters

High Current Low Voltage DC/DC Converters

This device also supports supply input under voltage

lockout. The uP1959 is available in thermally enhanced

WDFN2x2 - 8L and WDFN3x3 - 8L packages.
