The TPS61166DSKT is an LED driver IC specifically designed for Power Management In Company (PMIC). It is particularly suited for automotive and industrial applications such as backlighting and driving of LED lamps. The device features an integrated buck boost DC-DC converter, PWM dimming control, and a programmable current source.

The TPS61166DSKT is gimballed to operate over a wide range of input voltage, up to 18.5V. It can regulate the output current across a wide range of values, making it a perfect device for powering small to medium-sized LED applications. It provides extensive protection features, including safe area control, over temperature protection, cycle-by-cycle current limiting and output short circuit protection.

The current level inside the device is accurately controlled using a dedicated voltage comparator. This comparator outputs a signal that adjusts the LED current accordingly. The LED current is then regulated using an internal MOSFET switch. This approach ensures that the LED current is accurately regulated over a wide range of input and output voltages. As a result, high-efficiency operation is possible.

The TPS61166DSKT can be easily programmed to alter the dimming cycle, giving designer’s great flexibility. When driven directly with a PWM signal, the device accurately dims the LED in accordance with the PWM duty cycle. Alternatively, a linear dimming control can be used. On-board protection features guard against damage due to over temperature, overload and short circuit conditions.

The TPS61166DSKT is an excellent choice for LED backlighting and other LED-driven systems. Its integrated buck-boost DC-DC converter, programmable current source, and safety features make it suitable for a wide range of automotive and industrial applications. High-efficiency operation, fast transient response, and a wide range of input and output voltage compatibility make it a perfect device for LED lighting applications.
