Overview
The TPS60230RGTR is a five-channel white LED charge pump current source manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 6.5 V and provides a regulated output voltage of 5.5 V. Each channel delivers up to 125 mA of output current, with a typical per-channel limit of 25 mA for specific backlight configurations. The device utilizes a 1 MHz switching frequency and features PWM dimming control. It is housed in a 16-pin VQFN package (3x3 mm) with an exposed pad, designed for surface-mount installation across an operating temperature range of -40°C to +85°C.
Feature Summary
- Five independent high-current channels optimized for matching white LED supplies
- Integrated PWM brightness control for precise display backlight regulation
- Switched capacitor topology providing efficient step-up conversion without inductors
Applications
- Backlight drivers for color displays
- White LED current source applications
- Portable electronic device illumination systems
Procurement Notes
Verify the component marking against official Texas Instruments datasheets to confirm authenticity. Ensure the received package matches the specified 16-VQFN (3x3) footprint. Check for moisture sensitivity labeling as indicated in manufacturer documentation. Confirm that the revision suffix aligns with the required supply chain specifications.
Selection Notes
Select this component when designing multi-channel white LED backlights requiring tight current matching. It is suitable for applications needing inductor-less boost conversion from single-cell lithium-ion or similar power sources. Consider the thermal performance of the exposed pad design for heat dissipation in compact enclosures.
Part Context
This part belongs to the TPS60230 series of charge pumps. It is functionally related to the TPS60230RGTT variant, differing primarily in packaging format. The series is categorized under PMIC power management ICs, specifically targeting LED driver solutions for portable consumer electronics.
Replacement Considerations
The TPS60230RGTT is a documented alternative within the same family, offering identical electrical characteristics but in a tape-and-reel tray format rather than standard reel packaging. Verify pin compatibility before substitution.
