TPS65070RSLR

The Texas Instruments TPS65070RSLR is a versatile Power Management IC (PMIC) tailored for portable applications. It features a comprehensive power solution including a battery charger with power path management, capable of delivering 2A on the power path and a maximum charge current of 1.5A. The device integrates three highly efficient 2.25MHz step-down converters, each capable of up to 1.5A output current, suitable for core voltage, memory, and I/O voltage requirements in processor-based systems.

Additionally, the TPS65070RSLR includes two general-purpose LDOs, each providing up to 200mA output current. These LDOs can be dynamically scaled and are suitable for powering interfaces like SD cards or always-on rails. The PMIC also incorporates a wLED boost converter with internal dimming capabilities via I2C, supporting up to two strings of white LEDs.

Designed for a wide input voltage range of 2.8V to 6.3V (for converters) and 1.8V to 6.3V (for LDOs), this IC operates within an ambient temperature range of -40°C to 85°C. It comes in a compact 48-VQFN (6x6mm) package, making it ideal for space-constrained designs. The step-down converters offer adjustable or fixed output voltages and feature a power-save mode at light loads for enhanced efficiency, with typical quiescent currents of 19μA per converter.
