MAX1623EAP+T Description

Short technical summary and product information.

The MAX1623EAP+T from Analog Devices (formerly Maxim Integrated) is a low-voltage, step-down (buck) switching regulator designed for applications requiring efficient power conversion. It delivers a continuous load current of up to 3A.

 

This regulator operates with an input voltage range of 4.5V to 5.5V and provides an adjustable output voltage from 1.1V to 3.8V. It features internal switches, including a 55mΩ PMOS power switch and a 60mΩ NMOS synchronous-rectifier switch, contributing to its high efficiency of up to 94% and simplifying external component count.

 

The MAX1623EAP+T utilizes constant-off-time, current-mode PWM control with switching frequencies up to 350kHz. It offers ±1% output accuracy, including line and load regulation. The device is available in a compact 20-pin SSOP package, suitable for space-constrained designs.

 

Key features include thermal shutdown protection and Idle Mode operation at light loads. This regulator is well-suited for applications such as 5V to 3.3V conversion, notebook computer CPU I/O supplies, and desktop computer bus-termination supplies.
