MAX638AESA-T Description

Short technical summary and product information.

The MAX638AESA-T is a versatile Buck Switching Regulator IC manufactured by Analog Devices / Maxim Integrated. Designed for efficient DC to DC conversion, this component operates with a switching frequency of 65kHz.

 

Key electrical specifications include a minimum input voltage of 2.2V and a maximum input voltage of 16.5V. The output voltage is adjustable and positive, with a maximum output voltage of 16.5V and a maximum output current of 75mA. The device is designed for step-down (buck) topology and does not feature a synchronous rectifier.

 

This regulator is housed in an 8-SOIC package with surface mount mounting type. It is designed to operate across a wide temperature range, from -40°C to 85°C. The compact dimensions of 5mm x 4mm x 1.5mm make it suitable for space-constrained applications.
