The MAX5053AEUA-T is a current-mode PWM controller designed for step-up (boost) DC-DC power supplies. It is suitable for low-input voltage applications, operating from 10.8VDC to 24VDC. This controller integrates an error amplifier for primary-side regulation, eliminating the need for an optocoupler in isolated power supplies.
Key electrical specifications include a switching frequency of 262kHz and a maximum duty cycle of 50%. It features digital soft-start to reduce output voltage overshoot and an internal thermal shutdown circuit to protect the device. The operating temperature range is -40°C to +85°C.
The device is available in a compact 8-pin µMAX package, making it suitable for space-constrained designs. It is designed for surface mount applications. The MAX5053AEUA-T is part of a series of PWM controllers that offer flexibility in designing isolated and non-isolated power supplies.
