MAX5071 - (MAX5070 / MAX5071) Current-Mode PWM Controllers

This page provides the datasheet information for the MAX5071, a member of the MAX5070 (MAX5070 / MAX5071) Current-Mode PWM Controllers family.

Description

The MAX5070/MAX5071 BiCMOS, high-performance, current-mode PWM controllers have all the

Features

  • required for wide input voltage range isolated/nonisolated power supplies. These controllers are used for low- and high-power universal input voltage and telecom power supplies. The MAX5070/MAX5071 contain a fast comparator with only 60ns typical delay from current sense to the output for overcurrent protection. The MAX5070A/MAX5070B have an integrated error amplifier with the output at COMP. Soft-start is achieved by controlling the COMP voltage rise using external components. The frequency is.

The MAX5070A/MAX5070B have an integrated error amplifier with the output at COMP. Soft-start is achieved by controlling the COMP voltage rise using external components. The frequency is adjustable from 20kHz to 1MHz with an external resistor and capacitor.
