Overview
The TPS60230RGTT is a five-channel charge pump current source designed for white LED backlighting in color displays. It operates within an input voltage range of 2.7 V to 6.5 V and delivers a regulated output current of 125 mA per channel. The device features a 1 MHz switching frequency and supports PWM dimming control. It is housed in a 16-pin VQFN package with dimensions of 3x3 mm, suitable for surface-mount applications across a temperature range of -40°C to +85°C.
Feature Summary
- Five independent channels provide constant current regulation for white LED arrays
- Integrated PWM brightness control interface for display applications
- Optimized topology ensures high efficiency for backlit color display supplies
Applications
- White LED backlighting for color displays
- Portable electronic devices requiring multi-channel LED drivers
- Industrial instrumentation with LCD backlight requirements
Procurement Notes
Verify the specific suffix RGTT against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure compatibility with the required thermal management solutions for the VQFN-EP-16 package. Cross-reference the datasheet revision history to validate electrical characteristics and pinout assignments before finalizing procurement specifications.
Selection Notes
Select this component when designing systems requiring five synchronized LED channels with precise current matching. The integrated charge pump architecture eliminates the need for external inductors, simplifying PCB layout. Consider the 125 mA per channel capability relative to the total power dissipation limits of the 3x3 mm package under maximum operating temperatures.
Part Context
This part belongs to the TPS60230 family of charge pump current sources manufactured by Texas Instruments. The series is specifically engineered for portable electronics, offering a compact solution for driving multiple LEDs without magnetic components. The RGTT designation indicates a specific reel quantity and packaging variant within the broader product line.
Replacement Considerations
Consult official substitution guides for compatible alternatives such as the TPS60230RGTR, which shares identical electrical specifications but differs in packaging format. Verify pin-to-pin compatibility and thermal performance metrics before implementing any substitute components in existing designs.
