FEATURES

DESCRIPTION

The LM5030 High Voltage PWM controller contains

2

•

Internal High Voltage Start-up Regulator

all of the features needed to implement Push-Pull and

•

Single Resistor Oscillator Setting

Bridge topologies, using current-mode control in a

•

Synchronizable

small 10 pin package. This device provides two

alternating gate driver outputs. The LM5030 includes

•

Error Amplifier

a high-voltage start-up regulator that operates over a

•

Precision Reference

wide input range of 14V to 100V. Additional features

•

Adjustable Softstart

include: error amplifier, precision reference, dual

mode current limit, slope compensation, softstart,

•

Dual Mode Over-Current Protection

sync capability and thermal shutdown. This high

•

Slope Compensation

speed IC has total propagation delays less than

•

Direct Optocoupler Interface

100ns and a 1MHz capable single resistor adjustable

oscillator.

•

1.5A Peak Gate Drivers

•

Thermal Shutdown

Package:

VSSOP-10

and

thermally

enhanced

WSON-10 (4mm x 4mm).

APPLICATIONS

•

Telecommunication Power Converters
