Integrated Handheld Battery and Power Management
The programmable TPS65800 delivers high DC/DC conversion efficiency and battery management to one-cell, lithium-ion-powered communication and multimedia devices with multiple voltages, such as smart phones, portable media players, satellite radio and GPS systems. And it occupies up to 70% less board space than discrete solutions.
The TPS65800's dynamic power path management technology allows the IC to power the system while independently charging a one-cell, Li-Ion battery from either a USB or AC/DC wall adapter power source—all without adding any external power components.
To conserve battery power, the DC/DC switch-mode converters support greater than 90% efficiency over a wide range of load currents while deploying pulse frequency modulation at light-load conditions.
