LM5030

100V Push-Pull Current Mode PWM Controller

General Description

The LM5030 High Voltage PWM controller contains all of the

features needed to implement Push-Pull and Bridge topolo-

gies, using current-mode control in a small 10 pin package.

This device provides two alternating gate driver outputs. The

LM5030 includes a high-voltage start-up regulator that oper-

ates over a wide input range of 14V to 100V. Additional

features include: error amplifier, precision reference, dual

mode current limit, slope compensation, softstart, sync ca-

pability and thermal shutdown. This high speed IC has total

propagation delays less than 100ns and a 1MHz capable

single resistor adjustable oscillator.

Package: MSOP-10 (Contact factory for thermally enhanced

LLP availability).
