Linear Technology Corporation announces the LTC3557,
a multi-function power management solution for Li-Ion/Polymer battery applications. The LTC3557 integrates a linear PowerPath™ manager, a standalone battery charger, ideal diode, three high efficiency synchronous buck regulators and an always-on LDO in a low-profile
4mm x 4mm QFN package. The powerpath manager seamlessly manages the transition between multiple input sources and power to the load, while for fast charging the linear battery charger delivers up to 1.5A charge current from a wall adapter supply or up to 500mA charge current from a USB port.
