The TPS6507x are single chip Power Management ICs for portable applications consisting of a battery charger with power path management for a single Li-Ion or Li-Polymer cell. The charger can either be supplied by a USB port on pin USB or by a dc voltage from a wall adapter connected to pin AC. Three highly efficient 2.25MHz step-down converters are targeted at providing the core voltage, memory and I/O voltage in a processor based system. The step-down converters enter a low power mode at light load for maximum efficiency across the widest possible range of load currents. For low noise applications the devices can be forced into fixed frequency PWM using the I2C interface. The step-down converters allow the use of small inductors and capacitors to achieve a small solution size. The TPS6507x also integrate two general purpose LDOs for an output current of 200mA. These LDOs can be used to power an SD-card interface and an always-on rail, but can be used for other purposes as well. Each LDO operates with an input voltage range between 1.8V and 6.3V allowing them to be supplied from one of the step-down converters or directly from the main battery. An inductive boost converter with two programmable current sinks power two strings of white LEDs.

The TPS6507x come in a 48-pin leadless package (6mm × 6mm QFN) with a 0.4mm pitch.
