SYNCHRONOUS BOOST CONVERTER WITH DOWN MODE  
HIGH POWER WHITE LED DRIVER  
FEATURES  
DESCRIPTION  
•
80% Efficient Synchronous Boost Converter  
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.  
– 500-mA LED Current From 3.3-V Input  
(TPS61058)  
– 800-mA LED Current From 3.3-V Input  
(TPS61059)

Input Voltage Range: 2.7 V to 5.5 V  
Fixed Frequency 650 kHz (Typ) Operation  
LED Disconnect During Shutdown  
Open/Shorted LED Protection  
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).  
Over-Temperature Protection  
Low Shutdown Current: 100 nA (Typ)  
Total Solution Of Less Than 80 mm2  
Small 3mm x 3mm QFN-10 Package  
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 µA. Built-in precharge and soft-start  
circuitry prevents excessive inrush current during  
start-up.  
APPLICATIONS  
•
Torch/Camera White LED Supply for Cell  
Phones, Smart-Phones and PDAs  
The device is packaged in  
a
10-pin QFN  
PowerPAD™ package measuring 3 mm x 3 mm  
(DRC).
