MAX5053BEUA Description

Short technical summary and product information.

The Analog Devices MAX5053BEUA is a current-mode PWM controller designed for isolated and non-isolated power supplies. It is well-suited for low-input-voltage applications, accepting an input range of 10.8VDC to 24VDC.

 

This controller features an internal error amplifier for primary-side regulation, eliminating the need for an optocoupler. It includes an input undervoltage lockout (UVLO) that is externally programmable and internal digital soft-start to reduce output voltage overshoot. The device also has an internal thermal shutdown circuit to protect against over-temperature conditions.

 

The MAX5053BEUA operates at a fixed switching frequency of 262kHz with ±12% accuracy, allowing for optimized magnetic and filter components. It offers a maximum duty cycle limit of 75%. The device is available in a compact 8-pin µMAX package and operates over a temperature range of -40°C to +85°C.

 

Key features include current-mode control, digital soft-start, and a 75% maximum duty-cycle limit. The surface mountable 8-uMAX/uSOP package makes it suitable for space-constrained designs.
