TheTPS92515HVDGQT is a high voltage LED driver offering a cost effective, precise and energy-saving solution in applications such as automotive lighting, LCD TV backlight, and so on. It integrates a high current gate driver, powering up to three LEDs in series while providing superior efficiency, reliability, and flexibility.

The device provides a low noise power system design by integrating a higher output current of up to 2A and a high efficiency charge pump for driving higher current LEDs. It has in-built surge protection and a frequency selection switch for operation in either 125kHz or 400kHz. The operating temperature range of the TPS92515HVDGQT is from -40°C to +125°C. Other features include an ultra-low quiescent current and LED short circuit protection.

The TPS92515HVDGQT works on the principle of Constant Current (CC), where the current to the LED load is continuously maintained at a constant level regardless of any variations in the input voltage or load. The controller maintains the CC output by converting the voltage to a constant current and compressing it accordingly. The current is adjustable by use of a resistor connected to the CTRL pin. The internal feedback ensures that the current remains constant during all operating conditions. The device also features turn-off protection, which prevents any damage to the LEDs from prolonged driving in the event of a fault condition.

The TPS92515HVDGQT is ideal for off-line or DC applications that require precise and constant current control. It is capable of operating in a wide input voltage range from 4V to 40V and offers over temperature protection. The device helps to reduce design complexity and system cost by offering integrated surge protection, a low component count and flexibility.

The TPS92515HVDGQT offers several advantages including high efficiency and thermal performance, a wide operating temperature range, fast response, and robust surge and short-circuit protection. The device also supports a variety of operating types, such as push-pull, totem-pole, boosting, and buck-boost. In addition, it is a highly integrated device with a small form factor, making it ideal for space-constrained applications.

The TPS92515HVDGQT is an ideal application for automotive lighting, LCD TVs, medical equipment and other such applications that require high voltage LED drivers. The device is also ideal for applications that require precise and constant current control, such as industrial, agricultural and advanced metering applications. The TPS92515HVDGQT is an innovative solution for LED lighting solutions, offering precision, flexibility and reliability.
