Texas Instruments TPS650243 Power Management ICs for Li-Ion Powered Systems TPS650243RHBRG4

The TPS650243RHBRG4 is a power management integrated circuit designed for Li-Ion and Li-Polymer powered systems. It features three highly efficient step-down converters capable of delivering output currents of 1.6 A, 1.0 A, and 0.8 A, with efficiencies reaching up to 97%. The output voltage options for the core voltage (VDCDC3) are selectable at 1.0 V or 1.2 V, while the memory voltage (VDCDC2) can be set to 1.8 V, 2.5 V, or adjustable. Additionally, the device includes two general-purpose 200-mA low-dropout (LDO) regulators and a 30-mA LDO for always-on applications. The TPS650243 operates with a quiescent current of 85 µA and features thermal shutdown protection. It is packaged in a compact 32-pin VQFN format, measuring 5 mm x 5 mm, and is rated for operation in temperatures ranging from -40°C to 85°C. This IC is suitable for applications in portable devices such as smartphones, digital cameras, and GPS systems, making it a versatile choice for engineers looking for efficient power management solutions in battery-operated devices.
