The application examples and reference designs shown in this document can be used to design flashlight and movie-light applications for 1.8-V and 2.8-V logic. The TPS61058/9 devices are optimized for driving high-power, single-cell white LEDs up to 800 mA from a 2.7-V to 5.5-V input. The LED current can be programmed to different levels (e.g., torch, flashlight) by a set of external resistors. The

When performing measurements on DC-DC converters using pulse frequency modulation(PFM)or any power save mode proper care must be taken to ensure that the measurements are accurate. An accurate PFM mode efficiency measurement is critical for systems which require high efficiency at low loads such as in smart home systems tablets wearables and metering.
