uP1952

12V MOSFET Drivers with Output Disable

for Single Phase Synchronous-Rectified Buck Converter

Features

General Description

The uP1952 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 load with 30ns transition time.

This device combined with uPI multi-phase buck PWM

Bootstrapped High-Side Driver

Adaptive Anti-Shoot-Through Protection

Circuitry

controller forms a complete core voltage regulator for

advanced micro-processors.

Tri-State Input for Bridge Shutdown

Output Disable Control Turns Off both

MOSFETs

The uP1952 features adaptive anti-shoot-through

protection that prevents cross-conduction of the external

MOSFET while maintains minimum deadtime for optimized

efficiency.

Under Voltage Lockout for Supply Input

PSOP - 8L and WDFN3x3 - 8L Packages

RoHS Compliant and Halogen Free

Both gate drives are turned off by pulling low OD# pin or

high-impedance at PWM pin, preventing rapid output

capacitor discharge during system shutdowns.

Applications

Other feature is supply input under voltage lockout. The

uP1952 is available in thermal enhanced PSOP-8L and

WDFN3x3-8L packages.
