MAX5022 Current-Mode PWM Controllers for Isolated Power Supplies

The MAX5021/MAX5022 current-mode PWM controllers contain all the control circuitry required for the design of wide input voltage range isolated power supplies. These devices are well suited for use in universal input (85VAC to 265VAC) off-line or telecom (-36VDC to -72VDC) power supplies. An undervoltage lockout (UVLO) circuit with large hysteresis coupled w.
