MAX797HESE+ Description

Short technical summary and product information.

The MAX797HESE+ is a high-performance, step-down DC-DC converter designed for main CPU power in battery-powered systems. It features a high input voltage rating of up to 40V, allowing operation with various battery configurations and AC adaptors.

 

This buck controller achieves up to 96% efficiency through synchronous rectification and Maxim's proprietary Idle Mode™ control scheme, extending battery life. It offers excellent dynamic response, correcting output transients within five 300kHz clock cycles. The device supports fixed-frequency PWM operation at 150kHz or 300kHz, reducing noise and RF interference.

 

Key features include adjustable output from 2.5V to 6V, preset 3.3V and 5V outputs up to 10A, and a 5V linear-regulator output. It also provides a precision 2.505V reference output. The MAX797HESE+ utilizes a unique bootstrap circuitry to drive N-channel MOSFETs, reducing system cost.

 

The controller is available in a 16-pin narrow SO package and is suitable for surface mount applications. It is designed for use in notebook and subnotebook computers, as well as industrial controls.
