Overview
The TPS61054DRCT is a Texas Instruments LED lighting driver IC featuring a synchronous boost converter topology. It provides a constant current output of 700 mA, suitable for high-power white LEDs. The device operates with an input voltage range of 2.5 V to 6 V and supports a maximum output voltage of 10 V. It utilizes a DSBGA-12 or VSON-10 package and functions within a temperature range of -40°C to +85°C. Key electrical parameters include a switching frequency of 2 MHz and a maximum supply current of 8.5 mA.
Feature Summary
- Integrated synchronous boost converter architecture optimized for LED driving applications
- Constant current output capability designed for high-power white LED illumination
- Supports PWM dimming control for precise brightness regulation
Applications
- High-power white LED driver circuits
- Portable lighting systems requiring compact power management
- Battery-powered LED illumination modules
Procurement Notes
Verify the specific package variant (DSBGA-12 or VSON-10) against design requirements, as datasheet references may vary by revision. Confirm that the I2C interface mentioned in some listings does not apply to this specific part number, which relies on PWM dimming. Ensure compatibility with the target input voltage range of 2.5 V to 6 V before integration into the final system design.
Selection Notes
Select this component when a dedicated LED driver with integrated boost conversion is required. It is appropriate for designs needing a fixed 700 mA output current without external current sensing resistors. Consider the small footprint and thermal performance if space constraints are critical. Compare against the TPS61052 if I2C control is necessary instead of PWM dimming.
Part Context
This part belongs to the TPS6105x series of LED drivers from Texas Instruments. It shares architectural similarities with the TPS61052 but differs in control interface and specific output characteristics. The DRCT suffix indicates a tape and reel packaging format, facilitating automated assembly processes for high-volume manufacturing environments.
Replacement Considerations
The TPS61054DRCR is a compatible alternative with identical electrical specifications but differs in packaging format. No other direct substitutes are confirmed in public documentation.
