Texas Instruments TPS65921 Integrated Power Management IC with 3 DC/DC's, 4 LDO's, USB HS Transceiver TPS65921B1ZQZR

The TPS65921B1ZQZR is an integrated power management IC designed to meet the power and peripheral requirements of OMAP application processors. It features three step-down DC/DC converters, capable of delivering up to 1.4 A for VDD1, and four configurable low-dropout (LDO) regulators with a maximum current of 220 mA per LDO. The device operates within a voltage input range of 2.7 to 4.5 V and includes a USB high-speed transceiver compliant with USB 2.0 standards. Additional functionalities include a 10-bit analog-to-digital converter (ADC), a real-time clock (RTC) with an alarm wake-up mechanism, and a keypad interface supporting up to 8x8 configurations. The TPS65921B1ZQZR also incorporates SmartReflex dynamic voltage management and thermal shutdown protection, ensuring efficient power management and device safety. The package is a 120-ball µBGA, suitable for applications in mobile phones, handheld devices, and other low-power DSP systems.
