The Analog Devices MAX1902EAI+T is a high-performance, buck-topology, step-down, switch-mode power supply controller. It is designed to generate logic-supply voltages in battery-powered systems, making it suitable for notebook computers and mobile communicators.
This device offers dual adjustable outputs ranging from 2.5V to 5.5V, along with a 12V/120mA linear regulator. It incorporates features such as on-board power-up sequencing, power-good signaling with delay, digital soft-start, and internal frequency-compensation networks. The MAX1902EAI+T achieves up to 97% efficiency through synchronous rectification and Maxim's proprietary Idle Mode control scheme, extending battery life.
Operating at a low-noise, fixed frequency of 333kHz or 500kHz, this controller reduces RF interference in sensitive applications. It is available in a 28-SSOP surface-mount package and operates within a temperature range of -40°C to 85°C.
