Overview
19-2142; Rev 1; 9/02
3A, 1MHz, DDR Memory Termination Supply
General Description
The MAX1809 is a reversible energy flow, constant-offtime, pulse-width modulated (PWM), step-down DC-DC converter.
It is ideal for use in notebook and subnotebook computers that require 1.
1V to 5V active termination power supplies.
This device features an internal PMOS power switch and internal synchronous rectifier for high efficiency and reduced component count.
The internal 90m Ω PMOS power switch and 70mΩ NMOS synchronous-rectifier switch easily deliver continuous load currents up to 3A.
The MAX1809 accurately tracks an external reference voltage, produces an adjustable output from 1.
1V to VIN, and achieves...
