LM5034

High Voltage Dual Interleaved Current Mode Controller

with Active Clamp

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

The LM5034 dual current mode PWM controller contains all

the features needed to control either two independent

forward/active clamp dc/dc converters or a single high cur-

rent converter comprised of two interleaved power stages.

The two controller channels operate 180˚ out of phase

thereby reducing input ripple current. The LM5034 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

dead-time of the active clamp gate drivers and adjustable

maximum PWM duty cycle reduce stress on the primary side

MOSFET switches. Additional features include program-

mable line under-voltage lockout, cycle-by-cycle current

limit, hiccup mode fault operation with adjustable restart

delay, PWM slope compensation, soft-start, and a 2 MHz

capable oscillator with synchronization capability.

Synchronizable oscillator

n Active clamp gate driver for P-channel MOSFETs

n Adjustable gate drive overlap time

n Programmable maximum duty cycle

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-20
