MAX1623EAP Description

Short technical summary and product information.

The MAX1623EAP is a versatile step-down (buck) switching regulator designed for low-voltage applications. It features internal switches, including a 55mΩ PMOS power switch and a 60mΩ NMOS synchronous-rectifier switch, enabling it to deliver continuous load currents up to 3A.

 

This regulator provides an adjustable output voltage ranging from 1.1V to 3.8V, with ±1% output accuracy including line and load regulation. It operates with a wide input voltage range of 4.5V to 5.5V and offers high efficiency up to 94%. The device utilizes constant-off-time, current-mode PWM control with switching frequencies as high as 350kHz, allowing for flexible design choices regarding switching noise and inductor size.

 

Designed for applications such as 5V to 3.3V conversion, notebook computer CPU I/O supplies, and desktop computer bus-termination supplies, the MAX1623EAP is available in a space-saving 20-pin SSOP package. It also includes features like thermal shutdown protection and Idle Mode™ operation at light loads, along with a low shutdown supply current of less than 1µA.

 

The MAX1623EAP is suitable for surface mount applications and operates within a temperature range of -40°C to 85°C.
