MAX5074 - Power IC with Integrated MOSFETs

General Description

The MAX5074 isolated PWM power IC

Key Features

  • integrated switching power MOSFETs connected in a voltageclamped, two-transistor, power-circuit configuration. This device can be used in both forward and flyback configurations with a wide input voltage range from 11V to 76V and up to 15W of output power. The voltage-clamped power topology enables full recovery of stored magnetizing and leakage inductive energy for enhanced efficiency and reliability. A lookahead signal for driving secondary-side synchronous rectifiers can be used to increase e.
