SNVS428H –JANUARY 2006–REVISED OCTOBER 2015

LM5035 PWM Controller With Integrated Half-Bridge and SyncFET Drivers

1 Features

3 Description

The LM5035 half-bridge controller-gate driver

contains all of the features necessary to implement

half-bridge topology power converters using voltage

mode control with line voltage feedforward. The

floating high-side gate driver is capable of operating

with supply voltages up to 105 V. Both the high-side

and low-side gate drivers are capable of 2-A peak. An

internal high voltage start-up regulator is included,

along with programmable line undervoltage lockout

(UVLO) and overvoltage protection (OVP). The

oscillator is programmed with a single resistor to

frequencies up to 2 MHz. The oscillator can also be

synchronized to an external clock. A current sense

input and a programmable timer provide cycle-by-

cycle current limit and adjustable hiccup mode

overload protection.
