The TPS65000-Q1 device is a single-chip power-management IC for portable applications.
This device combines 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 device can be forced into fixed-frequency
PWM through 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 a power-good status output that can be
used for sequencing. The LDOs can supply 300 mA, and can operate with an input voltage range from
1.6 V tp 6 V, thus 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, thus
allowing for design and sequencing flexibility.
The TPS65000-Q1 is available in a 16-pin leadless package (3-mm × 3-mm QFN).
