com 19-2590; Rev 1; 11/03 KIT ATION EVALU E L B A AVAIL Current-Mode PWM Controllers with an Error Amplifier for Isolated/Nonisolated Power Supplies General Description The MAX5052/MAX5053 current-mode PWM controllers contain all the control circuitry required for the design of wide-input-voltage isolated and nonisolated power supplies.
The MAX5052 is well suited for universal input (rectified 85VAC to 265VAC) or telecom (-36VDC to -72VDC) power supplies.
The MAX5053 is well suited for low-input-voltage (10.
8VDC to 24VDC) power supplies.
The MAX5052/MAX5053 contain an internal error amplifier that regulates the tertiary winding output voltage.
This implements a primary-side regulated, isolated power supply, eliminating the need for an optocoupler.
An input undervoltage lockout (UVLO) is provided for programming the input-supply start voltage and to ensure proper operation during brownout conditions.
The input-supply start voltage is externally programmable with a vol...
