TPS65920A2ZCHR
集成电源管理/音频编解码器（ TPS65930只） Integrated Power Management / Audio Codec TPS65930 Only
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.
