3 Description
The TPS65200 device integrates a high-efficiency,
USB-friendly switched-mode charger with OTG
support for single-cell Li-ion and Li-polymer batteries,
D+D- detection, a 50-mA fixed-voltage LDO, a high-
efficiency WLED boost converter, and high-accuracy
current-shunt monitor into a single chip.
The TPS65200 comes in a tiny, 2.8-mm × 2.6-mm,
36-pin, 0.4-mm pitch die size ball grid array
(DSBGA).
