Overview

The MAX1684/MAX1685 are high-efficiency, internal switch, pulse-width modulation (PWM) step-down switching regulators intended to power cellular phones, communicating PDAs, and handy-terminals. These devices deliver a guaranteed 1A output current from two lithium-ion (Li+) batteries. Their wide-input voltage range of 2.7V to 14V gives design flexibility and allows batteries to charge from a wall cube, since the ICs operate at the higher voltages that occur when the battery is removed. The output voltage is preset to 3.3V or can be externally adjusted from 1.25V to VIN.

Applications

Cellular Phones
Two-Way Radios and Walkie-Talkies
Computer Peripherals
Personal Communicators
PDAs and Handy-Terminals

Key features

High-efficiency, internal switch, pulse-width modulation (PWM) step-down switching regulators
Deliver a guaranteed 1A output current from two lithium-ion (Li+) batteries
Wide-input voltage range of 2.7V to 14V
Output voltage is preset to 3.3V or can be externally adjusted from 1.25V to VIN
Low on-resistance power switch and built-in synchronous rectifier provide high efficiencies of up to 96%
Four modes of operation: fixed-frequency, normal, low-power, and shutdown
Fixed-frequency PWM mode offers excellent noise characteristics
Normal mode maintains high efficiency at all loads
Low-power mode conserves power in standby or when full load is not required
Shutdown mode powers down the device for minimal current draw
MAX1684 runs at 300kHz for highest efficiency applications
MAX1685 runs at 600kHz to allow use of smaller external components
Can be synchronized to an external clock
100% duty cycle for low-dropout applications
Auxiliary 3V/5mA output
1% accurate reference
Available in a space-saving 16-QSOP package
Up to 96% Efficiency
