The TPS65950A3ZXN is a highly integrated Power Management and audio coder/decoder (codec) integrated circuit that supports the power and peripheral requirements of the OMAP™ application processors. The device contains power management, an audio codec, universal serial bus (USB) high-speed (HS) transceiver, an AC/USB charger, light-emitting diode (LED) drivers, an analog-to-digital converter (ADC), a real-time clock (RTC) and embedded power control. The power portion of the device contains three buck converters, two controllable by a dedicated SmartReflex class-3 interface, multiple low-dropout (LDO) regulators, an embedded power controller (EPC) to manage the power-sequencing requirements of OMAP and an RTC and backup module. The RTC can be powered by a backup battery when the main supply is not present and the device contains a coin-cell charger to recharge the backup battery as needed.
