MAX1626 Product details

Description

The MAX1626/MAX1627 step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA to more than 2A.

A unique current-limited, pulse-frequency-modulated (PFM) control scheme operates with up to a 100% duty cycle, resulting in very low dropout voltages.

Features

o Low Dropout Voltage o 100% Maximum Duty Cycle o Soft-Start Limits Start-Up Current o Efficiency >90% (3mA to 2A Loads) o Output Power >12.5W o 90µA Max Quiescent Current o 1µA Max Shutdown Current o Up to 300kHz Switching Frequency o 16.5V Max Input Voltage o Output Voltage: 5V/3.3V (MAX1626) Adjustable (MAX1627) o Current-Limited Control Scheme _______________General.
