TPS61085DGKTG4

The TPS61085DGKTG4 is a voltage regulator IC specifically designed to provide simple, efficient, and low power solutions for portable devices, such as smartphones, tablets, and wearables. The IC is part of the DC/DC switching regulator family from Texas Instruments and is a White LED driver with a programmable constant current. It facilitates the efficient operation of small lighting systems and is used largely in applications where a highly efficient and low power light source is needed.

The TPS61085DGKTG4 is designed to provide very efficient and high power conversion in a small, low-power format. It achieves this by operating as a synchronous step-down DC/DC converter with a programmable output voltage. It uses high-speed switching technology to regulate the output current and voltage in a very efficient manner, enabling it to be used in battery powered systems with long standby times. It also has very low quiescent current, making it ideal for ultra-low power applications. The TPS61085DGKTG4 has an adjustable switching frequency that can be programmed in a range of up to 200kHz. In addition, the device is EMI-friendly as its switching frequency is adjustable to adjust the switching noise.

The TPS61085DGKTG4 incorporates a logic enable pin which, when enabled, increases the voltage regulation accuracy by turning off the internal switching MOSFETs. In addition, the device has over-voltage, overload and thermal protection to ensure safe operation at the given outputs. It can also be used in battery-powered systems, as it is designed for low operating currents, and it can operate over a wide input voltage range of 2.7V to 5.5V.
