LM5032

High Voltage Dual Interleaved Current Mode Controller

General Description

Features

n Two independent PWM current mode controllers

n Integrated high voltage startup regulator

n Compound 2.5A main output gate drivers

n Single resistor oscillator setting to 2 MHz

n Synchronizable oscillator

The LM5032 dual current mode PWM controller contains all

the features needed to control either two independent for-

ward dc/dc converters or a single high current converter

comprised of two interleaved power stages. The two control-

ler 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 100V and

compound (bipolar + CMOS) gate drivers that provide a

robust 2.5A peak sink current. The adjustable maximum

PWM duty cycle reduce stress on the primary side MOSFET

switches. Additional features include programmable line

under-voltage lockout, cycle-by-cycle current limit, hiccup

mode fault operation with adjustable response time, PWM

slope compensation, soft-start, and a 2 MHz capable oscil-

lator with synchronization capability.

n Programmable maximum duty cycle

n Maximum duty cycle fold-back at high line voltage

n Adjustable timer for hiccup mode current limiting

n Integrated slope compensation

n Adjustable line under-voltage lockout

n Independently adjustable soft-start (each regulator)

n Direct interface with opto-coupler transistor

n Thermal shutdown

Applications

n Telecommunication Power Converters

n Industrial Power Converters

n +42V Automotive Systems

Packages

n TSSOP-16
