PMIC - LED Drivers are electrical power supplies that control and manage the power-on and power-off operations of a device’s lighting system. The TPS92641PWPR/NOPB is a precision, constant current, low-power, high-efficiency LED Driver that integrates a low-noise Linear regulator and a high voltage power FET with adjustable current limit and soft start-up. It is specifically designed to drive costly linear LED strips in automotive and industrial lighting applications.

The TPS92641PWPR/NOPB features an adjustable output current, an ultra low standby current, an efficiency of up to 95\%, and an operating temperature range from -40°C to +85°C. It offers a fast transient response, a wide operating voltage range from 7V to 25V, and is protected by a low voltage lockout, over temperature, and overload protection. It also includes a thermal overload protection and a current fold-back safety feature.

The TPS92641PWPR/NOPB supports a variety of applications, such as outdoor lighting, display lighting, stage lighting, architectural lighting, and automotive. It can be used to drive linear LED strips in automotive headlight, fog lights, daytime running lights, side markers, and tail lights. Additionally, it is also applicable in industrial and residential lighting applications, such as high bay and street lights.

The TPS92641PWPR/NOPB is designed to enable an LED lighting system to adjust its brightness using pulse density modulation or pulse width modulation. Pulse density modulation enables the lighting system to adjust its brightness by rapidly switching the LED load on and off at a specified frequency, while pulse width modulation enables the system to adjust its brightness by varying the on-time of the LED load within each cycle.

In addition, the TPS92641PWPR/NOPB is also capable of driven by dimmers and works with wall plug-in adapters for indoor applications and car batteries for automotive applications. The built-in Linear regulator also offers a low noise output voltage with maximum tolerance of 200mV, which makes it suitable for driving multiple LEDs in series, helping to easily achieve desired light intensity.

The TPS92641PWPR/NOPB is an advanced LED driver that combines the advantages of precision, low power, and electrical power efficiency. It provides a great level of precision, low thermal load, and a very low standby current. The adjustable output current ranging from 5mA to 1A, adjustable overload protection, and the adjustable soft start-up, further contribute to the efficiency and versatility of the TPS92641PWPR/NOPB.
