TPS65920A2ZCHR

TPS65920A2ZCHR is Texas Instruments’ highly integrated PMIC (power-management IC) designed for mobile/embedded systems. It provides multi-rail power management, battery charging, and system supervision for TI-based SoCs. Key points:
- Integrated buck regulators and LDOs to generate core, memory, and I/O rails, with sequencing and dynamic voltage scaling.
- Battery-charging/power-path block to safely charge a Li‑ion/polymer cell while supplying system power.
- I2C/SMBus control, fault protection (over-voltage, under-voltage, thermal), and watchdog/sleep modes.
- Programmable rails and monitoring to optimize efficiency and battery life.
The suffix A2ZCHR denotes a specific package variant (RoHS-compliant) and revision for this part; exact pinout and packaging details are in TI’s TPS65920A2ZCHR data sheet and product page. Typical applications include powering TI-based mobile/multimedia SoCs in smartphones, tablets, and other portable devices. For precise electrical specs and layout guidelines, consult the official TI documentation.

TPS65920A2ZCHR is TI’s highly integrated PMIC for mobile applications. Key features include:
