MAX5019 Current-Mode PWM Controllers with Integrated Startup Circuit

The MAX5019/MAX5020 integrate all the building blocks necessary for implementing DC-DC fixed-frequency power supplies. Either primary- or secondaryside regulation may be used to implement isolated or nonisolated power supplies. These devices are currentmode controllers with an integrated high-voltag.

MAX5019 Features

* o Wide Input Range: (18V to 110V) or (13V to 36V) o Isolated (without optocoupler) or Nonisolated Power Supply o Current-Mode Control o Leading-Edge Blanking o Internally Trimmed 275kHz ±10% Oscillator o Low External Component Count o Soft-Start o High-Voltage Startup Circuit o Pulse-by-Pulse Curren
