## Abstract

Systems and methods for extending operation of radio-frequency (RF) power amplifiers. In some embodiments, a method for fabricating a wireless device can be implemented. The method includes providing a flash LED driver and a radio-frequency block, coupling an output of the flash LED driver and the radio-frequency block and coupling the flash LED driver with a controller to allow the flash LED driver to provide boosted voltage to the radio-frequency block under a selected condition. Accordingly, the power amplifier can operate for a longer time when powered by a battery.

## Claims

### Claim 1

A method for fabricating a wireless device, the method comprising:
providing a flash LED driver and a radio-frequency block;
coupling an output of the flash LED driver and the radio-frequency block;
coupling the flash LED driver with a controller to allow the flash LED driver to provide boosted voltage to the radio-frequency block under a selected condition.
