Description

The TPS61058/9 devices are fixed frequency,synchronous boost dc-dc converters with an integrated down conversion mode. The TPS61058/9 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 of TPS61058/9 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 of TPS61058/9 in the boost switch is limited to 1000 mA (TPS61058) and 1500 mA (TPS61059).

The TPS61058/9 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 of TPS61058/9 prevents excessive inrush current during start-up.

The TPS61058/9 is packaged in a 10-pin QFN PowerPAD™ package measuring 3 mm x 3 mm (DRC).
