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%.

The small 10 pin LLP-10 package with exposed pad provides for efficient thermal management. Two alternating gate driver outputs with a guaranteed deadtime are provided. 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.
