1.3 Description
The TPS65920 and TPS65930 devices are power-management ICs for OMAP™ and other mobile
applications. The devices include power-management, a universal serial bus (USB) high-speed (HS)
transceiver, light-emitting diode (LED) drivers, an analog-to-digital converter (ADC), a real-time clock
(RTC), and an embedded power control (EPC). In addition, the TPS65930 includes a full audio codec with
two digital-to-analog converters (DACs) and two ADCs to implement dual voice channels, and a stereo
downlink channel that can play all standard audio sample rates through a multiple format inter-integrated
sound (I2S)/time division multiplexing (TDM) interface.
These optimized devices support the power and peripheral requirements of the OMAP application
processors. The power portion of the devices contains three buck converters, two controllable by a
dedicated SmartReflex class-3 interface, multiple low dropout (LDO) regulators, an 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 devices include a coin-cell charger to
recharge the backup battery as needed.
