3 Description

The LM5030 high-voltage PWM controller contains all

of the features needed to implement push-pull and bridge topologies, 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 operates over a wide input range of 14 V to 100 V. Additional features

include: error amplifier, precision reference, dual

mode current limit, slope compensation, softstart,

sync capability, and thermal shutdown. This high

speed IC has total propagation delays less than 100 ns and a 1-MHz capable single-resistor

adjustable oscillator.
