Overview
The TPS60255RTET is a high-efficiency, constant-frequency charge pump DC/DC converter designed for driving seven white LEDs. It operates within an input voltage range of 2.7 V to 6 V and delivers up to 175 mA per channel. The device integrates an EasyScale 1-Wire interface for analog dimming and supports auto-switching between 1× and 1.5× modes. Packaged in a 16-pin WQFN (3x3 mm) case, it functions across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a high-efficiency charge pump with automatic mode switching between 1× and 1.5× configurations.
- Features an EasyScale 1-Wire interface enabling precise analog dimming control via a single pin.
- Includes integrated LDO current regulators and fault detection mechanisms for reliable LED operation.
Applications
- LED backlight drivers
- Portable electronic devices requiring multi-channel LED illumination
Procurement Notes
Verify the component marking against official Texas Instruments documentation to confirm authenticity. Ensure the package matches the specified 16-WQFN (3x3 mm) dimensions. Confirm compliance with RoHS directives as indicated in the manufacturer's specifications before integration into production designs.
Selection Notes
Select this component for applications requiring efficient power management for multiple series-connected LEDs from a single-cell battery source. The 1-Wire interface simplifies system design by reducing control pin requirements. Verify that the required LED forward voltage aligns with the charge pump output capabilities within the specified input voltage range.
Part Context
This part belongs to the TPS60255 family of LED lighting drivers manufactured by Texas Instruments. It is specifically engineered for portable applications where space constraints and power efficiency are critical. The RTET suffix denotes the specific tape-and-reel packaging configuration for surface-mount assembly.
Replacement Considerations
TPS60255RTERG4 is a verified equivalent variant within the same product family, differing primarily in lead-free manufacturing compliance while maintaining identical electrical characteristics and functionality.
FAQ
