MAX5094A - Maxim Integrated Products

MAX5094A (MAX5094x / MAX5095x) Current-Mode PWM Controllers

The MAX5094A/B/C/D/MAX5095A/B/C BiCMOS, highperformance, 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 MAX5094/MAX5095 contain a fast comparator with only 60ns typical delay.

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 MAX5094/MAX5095 contain a fast comparator with only 60ns typical delay from current sense to the output for overcurrent protection. The MAX5094 has an integrated error amplifier with the output at COMP. Softstart is achieved by controlling the COMP voltage rise using external components. The oscillator frequency is adjustable from 20kHz to 1MHz with an external resistor and capacitor. The timing capacitor discharge.
