The TPS61046YFFT is a PMIC (Power Management Integrated Circuit) specifically designed to drive LEDs. It is part of the family of LED Driver products offered by Texas Instruments. The TPS61046YFFT is suitable for a variety of lighting applications, including automotive, consumer electronics, and lighting fixtures of all types. Its capability makes it particularly useful for applications where high efficiency, small form factor, and low cost are key requirements.

The TPS61046YFFT is an integrated circuit that contains the components necessary to drive a string of LEDs. For example, it contains a boost converter, a control logic, and a FET (Field Effect Transistor) to switch inductor current. The onboard boost converter provides a current regulated output, meaning that the LEDs are driven at the same regulated current regardless of input voltage variations. Additionally, because the boost converter is integrated, the need for external components (such as switching transistors, resistors, and capacitors) is eliminated.

The TPS61046YFFT comes in small, compact packages and provides high efficiency through its built-in boost converter. The device’s built-in FET provides constant LED current over its operating range, and its high-side current sensing eliminates the need for external current-sensing resistors. The user can also adjust the output voltage and the current limit using external resistors.

The device supports direct or constant-current operation and provides thermal shutdown for fault protection. It can also be configured for various working modes, including linear dimming, PWM dimming, and timed dimming. The device’s wide VIN-range of 3.2V to 20V provides great flexibility and allows it to be used in a variety of applications.

In addition to being an efficient and cost-effective solution, the TPS61046YFFT is a very reliable device. The onboard thermal protection and programmable current-limit prevents the circuit from overheating and makes it highly reliable. The device also has built-in short-circuit protection, which shuts down the output if a short-circuit is detected.

The TPS61046YFFT is an ideal solution for driving strings of LEDs in high efficiency and cost effective applications. Its small form factor and wide input voltage range make it ideal for a wide range of applications, including automotive, consumer electronics, and lighting fixtures. Its robust design and built-in protection features make it highly reliable for many years of trouble-free operation.
