Overview
The TPS60231RGTR is a three-channel white LED charge pump current source with PWM brightness control, manufactured by Texas Instruments. It operates from a supply voltage range of 2.7V to 6.5V and delivers up to 25mA per channel, totaling 75mA across all outputs. The device features regulated output current with 0.4% matching accuracy and utilizes a boost topology with an internal switching frequency of 1MHz. Packaged in a 16-VQFN (3x3) surface-mount case, it supports PWM dimming for backlight applications.
Feature Summary
- Three independent regulated current channels optimized for white LED supplies
- Integrated PWM brightness control interface
- High current matching accuracy of 0.4% between channels
- Internal power switches eliminate external inductor requirements
Applications
- Color display backlighting
- White LED driver circuits
- Portable electronic device illumination
Procurement Notes
Verify the specific suffix 'RGTR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the 16-VQFN package dimensions align with the PCB footprint design. Ensure the input voltage range of 2.7V to 6.5V matches the system power supply constraints before finalizing procurement.
Selection Notes
Select this component when three isolated LED channels are required with precise current matching. It is suitable for designs needing PWM dimming without external controllers. Consider the 16-VQFN package size for space-constrained layouts. Verify thermal performance within the -40°C to 85°C operating range for the target environment.
Part Context
This part belongs to the TPS60231 family of charge pump drivers. It shares architectural similarities with the TPS60230 but offers three channels instead of five. Both devices utilize the same 16-VQFN package and support similar input voltage ranges. The TPS60231 series is specifically engineered for high-efficiency white LED backlighting in portable electronics.
Replacement Considerations
The TPS60231RGTT is a parameter-equivalent alternative available in cut-tape packaging. Both parts share identical electrical specifications and pinouts. Verify that the packaging difference does not impact automated assembly processes.
