LM5033,pdf datasheet (100V Pus

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%. 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.
