Overview
The TPS61060YZFT is a constant current LED driver IC from Texas Instruments, housed in an 8-DSBGA package. It operates as a 1 MHz boost converter with an input voltage range of 300 mV to 7 V and supports up to 400 mA switch current. The device features digital brightness control and PWM dimming capabilities. It includes load disconnect during shutdown and offers overvoltage and short-circuit protection. The operating temperature range spans from -40°C to +85°C.
Feature Summary
- Integrated digital brightness control for single-wire communication
- PWM dimming capability for precise light intensity adjustment
- Load disconnect function during shutdown mode
- Built-in overvoltage and short-circuit protection mechanisms
Applications
- White LED power supplies
- Portable electronic device backlighting
- General LED lighting applications requiring brightness control
Procurement Notes
Verify the specific suffix 'YZFT' against the manufacturer's official datasheet to confirm the exact packaging configuration and tape-and-reel specifications. Ensure compatibility with the required input voltage range and thermal management requirements for the target application environment before finalizing procurement.
Selection Notes
Select this component when a compact solution for driving white LEDs with integrated digital or PWM dimming is required. It is suitable for space-constrained designs due to the small DSBGA footprint. Consider the wide input voltage range and high switching frequency for efficient power conversion in battery-powered systems.
Part Context
This part belongs to the TPS61060 series of LED drivers designed for portable applications. It integrates a boost converter with dedicated control logic for LED brightness management. The series is characterized by its ability to operate from low input voltages while providing stable constant current output for LED strings.
Replacement Considerations
Check for alternative packages within the same family, such as TPS61060DRBR (SON-8), if pinout compatibility or different thermal performance is needed. Verify that substitute components maintain the same 1 MHz switching frequency and digital control interface requirements.
