Overview
The TPS60250RTER is a high-efficiency charge pump LED lighting driver IC from Texas Instruments. It features seven outputs with a maximum output current of 230 mA and an output voltage of 6.5 V. The device operates on a power supply ranging from 3 V to 6 V, utilizing a switching frequency of 750 kHz. Packaged in a WQFN-16 (3x3 mm) format, it supports I2C interface control for dimming applications.
Feature Summary
- Integrates a switched capacitor charge pump topology optimized for high efficiency in LED driving applications.
- Provides seven independent output channels capable of delivering up to 230 mA per channel.
- Supports digital control via an I2C interface for precise brightness adjustment and operational management.
Applications
- LED backlighting systems
- High efficiency LED driver circuits
- Portable electronic display illumination
Procurement Notes
Verify the specific suffix 'RTER' against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with I2C bus voltage levels and check for RoHS compliance status as documented in the manufacturer's release notes before finalizing procurement orders.
Selection Notes
Select this component when designing multi-channel LED arrays requiring a compact solution without external inductors. The integrated charge pump design simplifies layout compared to inductive converters. Consider the 750 kHz switching frequency for EMI constraints and ensure the input voltage range aligns with the system's power source capabilities.
Part Context
This part belongs to the TPS60250 series of LED lighting drivers. It is distinct from buck-boost regulators like the TPS630250, focusing instead on stepped-up voltage conversion via capacitive switching for low-power, high-density LED illumination tasks.
Replacement Considerations
Consult the TI product selection guide for direct pin-to-pin or functional equivalents within the TPS60250 family. Verify that alternative parts maintain the same 7-output architecture and I2C control interface requirements.
