Overview
The TPS60231RGTT is a three-channel charge pump DC-DC regulator designed for white LED backlight applications. It operates from a supply voltage range of 2.7V to 6.5V and provides regulated output currents up to 75mA per channel with 0.4% matching accuracy. The device integrates internal switches and supports PWM dimming control. It utilizes a 16-pin VQFN package (3x3mm) and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Three-channel current-regulated charge pump topology optimized for white LED supplies
- Integrated PWM brightness control interface for display backlighting
- High output current matching accuracy of 0.4% across channels
Applications
- Color display backlight systems
- White LED driver circuits
- Portable electronic device illumination
Procurement Notes
Verify the specific suffix 'RGTT' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the required output current does not exceed the 75mA limit per channel. Ensure the input voltage remains within the 2.7V to 6.5V operational window. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement.
Selection Notes
Select this component for designs requiring independent regulation of multiple white LEDs with tight current matching. It is suitable for space-constrained portable devices due to its compact 3x3mm QFN footprint. Consider thermal dissipation requirements if operating near maximum current limits. Verify compatibility with the system's PWM dimming signal levels.
Part Context
This part belongs to the TPS60231 series of charge pump regulators. It is distinct from buck or boost converters, specifically utilizing switched-capacitor technology to step up voltage while regulating current. The RGTT designation indicates a specific reel quantity and package configuration compared to other variants like RGTR.
Replacement Considerations
The TPS60231RGTR is a parameter-equivalent alternative differing primarily in packaging format (tape and reel vs. tube). No other direct functional substitutes are confirmed in the provided data.
