The TPS61061YZFT from Texas Instruments is a high-frequency, synchronous boost converter designed for constant current LED driving. It is capable of powering up to four white LEDs and features integrated overvoltage and short-circuit protection.
The device operates with a 1-MHz fixed switching frequency, enabling the use of small external components and simplifying EMI considerations. Brightness control is achieved through PWM signals applied to the enable pin or digital signals to the ILED pin. The output is disconnected during shutdown to prevent leakage current.
Key electrical specifications include an input voltage range of 2.7V to 6V, an internal switch current of 400mA, and a feedback voltage of either 500mV or 250mV. The operating temperature range is -40°C to 85°C.
This LED driver is supplied in an 8-DSBGA package and is suitable for surface mount applications. Its design makes it ideal for backlighting applications in portable electronic devices.
