Overview
The TPS61061YZFT is an LED lighting driver IC manufactured by Texas Instruments, designed for white LED power supplies. It functions as a boost converter with a switching frequency of 1 MHz and supports PWM dimming. The device features a single output capable of delivering up to 400 mA in switch mode. It operates within an input voltage range of 2.7 V to 6 V and provides an output voltage of 18.5 V. The component is housed in an 8-DSBGA package and is rated for operation between -40°C and +85°C.
Feature Summary
- Integrated overvoltage and short-circuit protection for enhanced reliability
- Supports PWM dimming for precise brightness control
- Compact 8-DSBGA package suitable for space-constrained designs
Applications
- LED backlighting systems
- White LED power supplies
- Portable electronic devices requiring LED illumination
Procurement Notes
Verify the specific suffix (YZFT) against the manufacturer's official documentation to confirm pinout, thermal characteristics, and tape-and-reel specifications. Ensure that the ordering code matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm compliance with current environmental standards such as RoHS. Confirm availability through authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a compact boost converter with integrated protection is required for driving white LEDs. Consider the 1 MHz switching frequency for smaller external passive components. Evaluate the 400 mA output capability against the target LED string requirements. Ensure the input voltage range aligns with the system's power source. Verify that the DSBGA-8 package fits within the mechanical constraints of the application.
Part Context
The TPS61061 belongs to a family of LED drivers from Texas Instruments designed for portable applications. Similar parts like the TPS61060 offer comparable functionality but may differ in output voltage or control features. This series emphasizes high efficiency and small footprint solutions for mobile and handheld devices. The YZFT designation indicates a specific package and temperature grade configuration within the broader product line.
Replacement Considerations
The TPS61060YZFR is a related component within the same family. Verify compatibility regarding output voltage levels and control interfaces before substitution. Ensure that any replacement part meets the same electrical and thermal requirements of the original design.
