TPS60230RGTTG4

Overview

The TPS60230RGTTG4 is a five-channel current-regulated charge pump designed for white LED backlight applications. It operates within an input voltage range of 2.7 V to 6.5 V and delivers up to 125 mA per channel. The device features a fixed switching frequency of 1 MHz and supports PWM dimming control. It is housed in a 16-pin VQFN package with dimensions of 3x3 mm, suitable for surface-mount assembly.

Feature Summary

• Provides independent current regulation across five output channels
• Integrates internal switches using switched capacitor topology
• Supports pulse-width modulation for display brightness control

Applications

• White LED backlighting for color displays
• Portable electronic device illumination systems
• Current source regulation for multi-LED arrays

Procurement Notes

Verify the suffix G4 indicates lead-free compliance when sourcing this component. Confirm the specific tape and reel packaging details required for automated assembly processes. Ensure the supplier provides valid RoHS documentation matching the manufacturer's specifications for environmental compliance.

Selection Notes

Select this component for designs requiring precise current matching across multiple LED channels. The integrated charge pump eliminates the need for external inductors, reducing board space. Consider the 1 MHz switching frequency for optimal trade-offs between efficiency and electromagnetic interference filtering requirements.
