Overview
The TPS60231RGTRG4 is a three-channel, current-regulated charge pump designed for white LED backlight applications. It provides regulated output currents of up to 25 mA per channel with 0.4% matching accuracy. The device operates within an input voltage range of 2.7 V to 6.5 V and delivers a maximum output voltage of 5.5 V. It features internal switches and supports PWM dimming control. The component is housed in a 16-VQFN package (3x3 mm) and functions across a temperature range of -40°C to 85°C.
Feature Summary
- Provides regulated output current with 0.4% matching accuracy for consistent LED brightness
- Drives up to three LEDs simultaneously at 25 mA each
- Supports LED brightness control through external PWM signals
Applications
- White LED backlighting for color displays
- Portable electronic devices requiring multi-LED illumination
- Battery-powered systems needing efficient DC-DC regulation
Procurement Notes
Verify the specific suffix G4 against official Texas Instruments documentation to confirm compliance with RoHS3 standards and material composition changes. Ensure the ordering part number matches the required tape-and-reel packaging configuration. Cross-reference the manufacturer product number with authorized distributors to validate authenticity and avoid counterfeit components during acquisition.
Selection Notes
Select this component when precise current matching between multiple LED channels is critical for uniform display lighting. It is suitable for designs requiring compact solutions due to its small QFN footprint. Consider the 1 MHz switching frequency and input voltage range when designing the external capacitor network. Ensure the application environment stays within the specified operating temperature limits.
Part Context
This part belongs to the TPS60231 family of charge pumps from Texas Instruments. It is specifically optimized for driving white LEDs in portable display backlights. The RGTRG4 designation indicates a specific reel quantity and RoHS-compliant variant within the broader TPS60231 series, sharing core electrical characteristics with other suffixes.
Replacement Considerations
TPS60231RGTT is a parameter-equivalent alternative available from Texas Instruments. Verify pin compatibility and thermal performance before substitution.
