MAX1636 Datasheet Low-voltage / Precision Step-down Controller

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-1268; Rev 0; 8/97 KIT ATION EVALU E L B A AVAIL Low-Voltage, Precision Step-Down Controller for Portable CPU.

General Description

The MAX1636 is a synchronous, buck, switch-mode, power-supply controller that generates the CPU supply voltage in battery-powered systems.

It achieves ±1% output voltage accuracy and offers the excellent loadtransient response needed by uping generations of dynamic-clock CPUs.

Up to 95% efficiency is achieved through synchronous rectification and Maxim’s proprietary Idle Mode™ control scheme.
