The MAX8662/MAX8663 power-management ICs
(PMICs) are efficient, compact devices suitable for
smart cellular phones, PDAs, Internet appliances, and
other portable devices. They integrate two synchronous
buck regulators, a boost regulator driving two to seven
white LEDs, four low-dropout linear regulators (LDOs),
and a linear charger for a single-cell Li-ion (Li+) battery.
Maxim's Smart Power Selector™ (SPS) safely distributes
power between an external power source (AC
adapter, auto adapter, or USB source), battery, and the
system load. When system load peaks exceed the
external source capability, the battery supplies supplemental
current. When system load requirements are
small, residual power from the external power source
charges the battery. A thermal-limiting circuit limits battery-charge rate and external power-source current to prevent overheating. The PMIC also allows the system to operate with no battery or a discharged battery.
The MAX8662 is available in a 6mm x 6mm, 48-pin thin
QFN package, while the MAX8663, without the LED driver,
is available in a 5mm x 5mm, 40-pin thin QFN package.
