High Power Single Cell White LED Driver With 1.1A Switch, In 3x3 QFN

The TPS61058 9 devices are fixed frequency, synchronous boost DC-DC Converters with an integrated down conversion mode. The 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 boost converter is based on a 650 kHz fixed frequency, pulse-width-modulation (PWM) controller using a synchronous Rectifier to obtain maximum efficiency. The maximum peak current in the boost Switch is limited to 1000 mA TPS61058 and 1500 mA TPS61059 .
The converter CAN be disabled to maximize battery life. In the shutdown mode, the load is completely disconnected and the current consumption is reduced to less than 1 ?A. Built-in precharge and soft-start circuitry prevents excessive inrush current during start-up.
The device is packaged in a 10-pin QFN PowerPAD? package measuring 3 mm x 3 mm (DRC).
