MAX5052, MAX5052A, MAX5052B, MAX5053, MAX5053A, MAX5053B Current-Mode PWM Controllers With An Error Amplifier For Isolated/Nonisolated Power Supplies

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 voltage-divider. To shutdown the device, the UVLO pin is pulled low. Internal digital soft-start reduces output voltage overshoot. The internal thermal shutdown circuit protects the device in the event the junction temperature exceeds +130C.
The MAX5052 has an internal bootstrap UVLO with large hysteresis that requires a minimum voltage of 23.6V for startup. The MAX5053 does not have the internal bootstrap UVLO and CAN be biased directly from a minimum voltage of 10.8V.

Filter components resulting in compact, cost-effective power supplies. The MAX5052A MAX5053A are offered with a 50% maximum duty-cycle limit. The MAX5052B MAX5053B are offered with a 75% maximum duty-cycle limit. These devices are available in 8-pin MAX packages and operate over the -40C to +85C temperature range.
