LM5033

100V Push-Pull Voltage Mode PWM Controller

General Description

Features

n Internal high voltage (100V) start-up regulator

n Single resistor oscillator setting

n Synchronizable

The LM5033 High Voltage PWM controller contains all the

features needed to implement Push-Pull, Half-Bridge, and

Full-Bridge topologies. Applications include closed loop volt-

age mode converters with a highly regulated output voltage,

or an open loop "DC transformer" such as an Intermediate

n Precision reference output

n Adjustable soft-start

n Over-current protection

n Direct optocoupler interface

n 1.5A peak gate drivers

Bus Converter (IBC) with an efficiency 95%. Two alternat-

ing gate driver outputs with a guaranteed deadtime are

provided. The LM5033 includes a start-up regulator that

operates over a wide input range of 15V to 100V. Additional

features include: precision voltage reference output, current

limit detection, remote shutdown, softstart, sync capability

and thermal shutdown. This high speed IC has total propa-

gation delays less than 100 ns and a 1MHz capable oscilla-

tor.
