General Description The MAX1684 MAX1685 are high efficiency internal switch pulse width modulation PWM step down switch ing 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 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 3V or can be externally adjusted from 25V to VIN The low on resistance power switch and built in synchro nous rectifier provide high efficiencies of up to There are four modes of operation: fixed frequency nor mal low power and shutdown The fixed frequency PWM mode of operation offers excellent noise character istics The normal mode maintains high efficiency at all loads The low power mode is used to conserve power in standby or when full load is not required The shutdown mode is used to power down the device for minimal cur rent draw The MAX1684 runs at 300kHz for applications that require highest efficiency The MAX1685 runs at 600kHz to allow the use of smaller external compo nents These devices can also be synchronized to an external clock Other features include a duty cycle for low dropout applications an auxiliary 3V 5mA output and a accurate reference Both devices are available in a space saving QSOP package An evaluation kit is also available to help speed designs For a similar device in a pin MAX package with lower input voltage requirements 5V max refer to the MAX1692 data sheet - Fe Campillo
