The MAX1631EAI from Analog Devices 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 proprietary Idle Mode™ control. This device offers dual adjustable outputs from 2.5V to 5.5V and includes features like power-up sequencing, power-good signaling, digital soft-start, and low-dropout circuitry.
Key electrical specifications include an input voltage range of 4.2V to 30V, a switching frequency of 200kHz to 300kHz, and a maximum duty cycle of 99%. It supports synchronous rectification and clock synchronization. The controller is designed for sensitive mobile communications and pen-entry applications, reducing noise and RF interference with its fixed-frequency PWM operation.
Packaged in a 28-SSOP, the MAX1631EAI is designed for surface mounting. Its operating temperature range is -40°C to 85°C (TA). The device is suitable for applications such as notebook and subnotebook computers, PDAs, mobile communicators, and desktop CPU local DC-DC converters.
