The TPS61165TDBVRQ1 from Texas Instruments is a high-brightness white LED driver designed for automotive applications. This boost converter IC features a 3V to 18V input voltage range and can deliver an output voltage up to 38V, making it suitable for series LED strings.
Key electrical specifications include a 1.2A switch current limit and a fixed switching frequency of 1.2MHz. It offers up to 90% efficiency and includes features like load disconnect during shutdown and synchronous rectification. Brightness control is flexible, supporting 1-wire digital (EasyScale™ protocol) and PWM dimming via the CTRL pin.
The device is housed in a compact SOT-23-6 package, suitable for surface mounting. It operates within an ambient temperature range of -40°C to 105°C. The internal MOSFET is rated for 40V, and the device provides 38V of open LED protection. The feedback voltage is regulated to 200mV with 2% accuracy, and the default LED current is set by an external resistor.
This LED driver is qualified for automotive applications and is ideal for use in backlighting and general illumination systems where high brightness and efficient power conversion are required.
