Overview
The TPS61059DRCT is a synchronous boost converter with an integrated high-power white LED driver manufactured by Texas Instruments. It features an internal 800mA switch and supports single-cell lithium-ion battery inputs ranging from 2.7V to 4.2V. The device delivers up to 800mA output current for driving LEDs, with a maximum output voltage of 30V. It operates at a fixed switching frequency of 2.2MHz and includes programmable dimming via PWM or analog control. The component is housed in a 10-pin VSON (3x3mm) package, designed for surface-mount installation within a temperature range of -40°C to +85°C.
Feature Summary
- Integrated synchronous boost topology with dedicated high-power LED driver functionality
- Supports both PWM and analog dimming methods for precise brightness control
- Internal 800mA power switch eliminates external component requirements for basic operation
- Fixed 2.2MHz switching frequency enables the use of compact passive components
Applications
- Mobile phone camera flash lighting systems
- LCD panel backlighting for portable devices
- General-purpose LED illumination in consumer electronics
Procurement Notes
Verify the specific suffix 'DRCT' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 10-VSON package dimensions align with the designated footprint on the printed circuit board. Ensure input voltage sources remain within the specified 2.7V to 4.2V range to prevent device malfunction or damage during operation.
Selection Notes
Select this component when designing circuits requiring high-efficiency boost conversion specifically for white LED applications. It is suitable for single-cell lithium-ion battery powered devices where space constraints necessitate a small form factor. Consider the 800mA current limit when determining the number of series-connected LEDs or required luminance levels for the target application.
Part Context
This part belongs to the TPS6105x family of synchronous boost converters optimized for LED driving. It shares architectural similarities with other TI LED drivers but is distinguished by its specific 800mA current capability and integration level. The DRCT suffix indicates a specific reel quantity and packaging variant distinct from cut-tape or tube options.
Replacement Considerations
Direct substitutes include TPS61059DRCR for alternative reel packaging. Cross-family alternatives may require evaluation of current limits and pin compatibility.
