Product Summary

The MAX1685EEE+T are high-efficiency, internalswitch, PWM step-down switching regulators intended to power cellular phones, communicating PDAs, and handy-terminals. The MAX1685EEE+T delivers a guaranteed 1A output current from two Li-Ion 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 MAX1685EEE+T output voltage is preset to 3.3V or can be externally adjusted from 1.25V to VIN. The MAX1685EEE+T runs at 600kHz to allow use of smaller external components. These devices can also be synchronized to an external clock. Other features include a 100% duty cycle for low-dropout applications, an auxiliary 3V/5mA output, and a 1% accurate reference.
