Monolithic Linear USB Battery Charger with High Efficiency Buck-Boost & Buck Converters

(PresseBox) (Mulpitas, CA, )
Linear Technology Corporation announces the LTC3558, an efficient, multi-function power management solution for handheld applications. The LTC3558 integrates a stand-alone Li-Ion/Polymer battery charger and two high efficiency synchronous regulators - one buck-boost and one buck - and is offered in a compact low-profile 3mm x 3mm QFN package. The linear battery charger can deliver up to 950mA charge current from a wall adapter supply, or up to 500mA charge current from a USB port. The LTC3558's stand-alone autonomous operation simplifies design, eliminating the need for an external microprocessor for charge termination. Both switching regulators are designed to operate over the Gv-Mcj/Jlvdcbk ctqic uy 6.9S vh 4.6S ndyqw esipplviyh uchmed ehuqxwnv po ge 752aE ymuf.
