DC DC Switching Controllers datasheet and documents for MAX1634EAI

MAX1634EAI

DC DC Switching Controllers Overview

The MAX1634EAI is a dual switching controller designed for notebook computer power supplies. It operates with an input voltage range of +4.2V to +30V and provides two adjustable outputs ranging from 2.5V to 5.5V. The device integrates a 12V linear regulator, a precision 2.5V reference, and a 5V/50mA linear regulator output. It utilizes current-mode control with pulse width modulation to achieve high efficiency.

DC DC Switching Controllers Feature Summary

Dual Mode operation allows selection between fixed 3.3V/5V outputs or fully adjustable regulation
Integrated secondary feedback capability enables precise adjustment of the secondary output voltage
Includes dedicated on-chip linear regulators providing stable 12V and 5V auxiliary rails

DC DC Switching Controllers Applications

Multi-output power supply controllers for notebook computers
Systems requiring simultaneous generation of multiple regulated DC voltages
Power management architectures utilizing Dual Mode selectable outputs
