The TPS6500xx devices are single-chip power management (PWM) ICs for portable applications. Both devices combine a single step-down converter with two low-dropout (LDO) regulators. The step-down converter enters 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 through a pin. The step-down converter is small because of its small inductor and capacitors. The step-down converter has power good status output for sequencing. The LDOs can supply 300 mA and operate with an input voltage range from 1.6 V to 6 V. A step-down converter or main battery can power the LDOs directly. The step-down converter and the LDOs have separate voltage inputs that enable maximum design and sequencing flexibility.

The TPS65001 extends functionality by adding a supply voltage supervisor (SVS). To maximize the flexibility of the SVS, the reset voltage is set with two external resistors and the reset time is set by a small external capacitor. For external control, the SVS can use its active-low manual reset input to connect to a push button.

The TPS65000 is available in a 16-pin leadless package (3 mm × 3 mm QFN). The TPS65001 is available in a 20-pin leadless package (3 mm × 3 mm QFN).
