The Texas Instruments TPS65000 and TPS65001 single chip power management ICs each combine a step down converter with two low dropout regulators. The step down converter in these TI power management ICs enters a low power mode at light load for maximum efficiency across the widest possible range of load currents. The step down converter also has Power Good status output that can be used for sequencing. The LDOs are capable of supplying 300mA and can operate with an input voltage range between 1.6V and 6V, allowing them to be supplied from the step down converter or directly from the main battery. The TI TPS65000 power management IC is available in a leadless 16-pin, 3mm x 3mm QFN package. The TI TPS65001 is available in a leadless 20-pin, 3mm x 3mm QFN package. The TPS65001 extends functionality by adding a Supply Voltage Supervisor.
