LM5033 100V Push-Pull Voltage Mode PWM Controller

Check for Samples: LM5033

FEATURES

PACKAGE

•

Internal High Voltage (100V) Start-Up

Regulator

•

VSSOP-10

WSON-10

•

Single Resistor Oscillator Setting

Synchronizable

DESCRIPTION

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 voltage mode converters with a

highly regulated output voltage, or an open loop "DC

transformer" such as an Intermediate Bus Converter

(IBC) with an efficiency >95%. Two alternating gate

driver outputs with a specified deadtime are provided.

Precision Reference Output

Adjustable Soft-Start

Over-Current Protection

Direct Optocoupler Interface

1.5A Peak Gate Drivers

Thermal Shutdown

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 propagation

delays less than 100 ns and a 1MHz capable

oscillator.
