The TPS65921 device is a highly integrated power-management circuit (IC) that supports the power and peripheral requirements of the OMAP application procesors. The device contains power management, a universal serial bus (USB) high-speed (HS) transceiver, an analog-to-digital converter (ADC), a real-time clock (RTC), a keypad interface, and an embedded power control (EPC). 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 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. Backup battery can be charged from the main battery. Up to 1.2 A of output current for DCDC1 TPS65921B supports DCDC1 up to 1.2 A TPS65921B1 will support DCDC1 up to 1.4 A SmartReflex? dynamic voltage management 3.2 MHz fixed frequency operation VIN range from 2.7 to 4.5 V
