Product Summary
The TPS61058DRCR is a fixed frequency, synchronous boost dc-dc converter with an integrated down conversion mode. The device is 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 applications of the TPS61058DRCR include Torch/Camera White LED Supply for Cell Phones, Smart-Phones and PDAs.
