LM5032

SNVS344B –MARCH 2005–REVISED DECEMBER 2014

LM5032 High-Voltage Dual Interleaved Current Mode Controller

1 Features

3 Description

The LM5032 dual current mode PWM controller

•

Two Independent PWM Current Mode Controllers

Integrated High-Voltage Startup Regulator

Compound 2.5-A Main Output Gate Drivers

Single Resistor Oscillator Setting to 2 MHz

Synchronizable Oscillator

contains all the features needed to control either two

independent forward dc/dc converters or a single high

current converter comprised of two interleaved power

stages. The two controller channels operate 180° out

of phase thereby reducing input ripple current. The

LM5032 includes a startup regulator that operates

over a wide input range up to 100 V and compound

(bipolar + CMOS) gate drivers that provide a robust

2.5-A peak sink current. The adjustable maximum

PWM duty cycle reduce stress on the primary side

MOSFET switches. Additional features include

programmable line undervoltage lockout, cycle-by-

cycle current limit, hiccup mode fault operation with

adjustable response time, PWM slope compensation,
