TPS65921 具有 3 个 DC/DC 电源、4 个 LDO、音频编解码器、USB HS 收发器的集成电源管理 IC
TPS65921 描述
The TPS65921/TPS65930 devices are power-management ICs for OMAPTM 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 embedded power control (EPC). In addition, the TPS65921 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 (I2STM)/time division multiplexing (TDM) interface.
These optimized devices support the power and peripheral requirements of the OMAP application processors
