The MAX1631EAI+ is a high-performance, dual-output, buck-topology, step-down, switch-mode power supply controller designed for battery-powered systems. It generates logic-supply voltages with up to 96% efficiency, achieved through synchronous rectification and Maxim's proprietary Idle Mode™ control scheme. This device offers excellent dynamic response, correcting output load transients within five 300kHz clock cycles.
Key features include a wide input voltage range of 4.2V to 30V, dual adjustable outputs from 2.5V to 5.5V, and a fixed 200kHz to 300kHz operating frequency. It supports synchronous rectification and has control features for enable, reset, and sequencing. The MAX1631EAI+ is housed in a 28-SSOP package and is designed for surface mount.
Applications for this controller include notebook and subnotebook computers, PDAs, mobile communicators, and desktop CPU local DC-DC converters. Its design focuses on extending battery life and reducing noise and RF interference in sensitive applications.
