The LM5033MM is a high-voltage mode Pulse Width Modulated (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 specified deadtime are provided. It includes a start-up regulator that operates over a wide input range of 15 to 100V. Additional features include: precision voltage reference output, current limit detection, remote shutdown, soft-start, sync capability and thermal shutdown. This high speed IC has total propagation delays less than 100ns and a 1MHz capable oscillator.
