MAX1951ESA+ Description

Short technical summary and product information.

The MAX1951ESA+ is a high-efficiency DC-to-DC step-down switching regulator designed by Analog Devices (formerly Maxim Integrated). It can deliver up to 2A of output current and operates from an input voltage range of 2.6V to 5.5V, providing an adjustable output voltage from 0.8V to V_IN. This makes it suitable for on-board post-regulation applications.

 

This regulator operates at a fixed frequency of 1MHz, which helps minimize the size of external components. It achieves an efficiency of up to 94%. The MAX1951ESA+ includes internal soft-start control circuitry to reduce inrush current and features short-circuit and thermal-overload protection for enhanced design reliability.

 

The device offers 1% output accuracy over load, line, and temperature for outputs up to 1.5A. It is available in a space-saving 8-pin SO package and is designed for surface mount applications. The operating temperature range is -40°C to 85°C.

 

Key applications include ASIC/DSP/µP/FPGA core and I/O voltages, set-top boxes, cellular base stations, and networking and telecommunications equipment.
