The TPS65000 and TPS65001 are single chip Power Management ICs for portable applications. Both devices combine a single step-down converter with two low dropout 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 via a pin. The step-down converter allows the use of a small inductor and capacitors to achieve a small solution size. The step-down converter 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 step-down converter and the LDOs have separate voltage inputs and enables, allowing for design and sequencing flexibility.
The TPS65000 is available in a 16-pin leadless package (3mm × 3mm QFN).
The TPS65001 extends functionality by adding a Supply Voltage Supervisor (SVS). The SVS allows maximum flexibility by having the reset voltage set with two external resistors, and the reset time set by a small external capacitor. In addition, an active low Manual Reset input allows the SVS to be connected to a push button for external control.
The TPS65001 is available in a 20-pin leadless package (3mm × 3mm QFN).
