Product Summary

The LM5030 is a High Voltage PWM controller containing 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 14V to 100V. 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 100ns and a 1MHz capable single resistor adjustable oscillator. The applications of the LM5030 include n Telecommunication Power Converters, Industrial Power Converters and +42V Automotive Systems.
