BD1603NUV-E2

The BD1603NUV-E2 is a PMIC - LED Driver which provides the user with a simple and efficient power supply solution for LED lighting. It is designed to reduce system cost and complexity by providing an integrated LED drive regulator solution.

The BD1603NUV-E2 has a wide range of applications in LED lighting, such as LED TVs, LCD monitors, and LED advertising displays. It is a high efficiency PMIC regulator, which can drive from 1W to 10W LED strings and is capable of driving up to 16 strings in parallel. It offers a high power factor and low THD operation for use in AC line operated LED lighting applications.

The BD1603NUV-E2 operates under open or closed loop operation, providing dynamic current for constant average luminance. It has an adjustable output in a wide range from 0.1V-Vout (VDC), up to 600mA. It supports dimming control from a wide range of standard dimmable sources such as 1-10V dimming, PWM dimming, and switch dimming, providing maximum flexibility for lighting control.

The BD1603NUV-E2 working principle is based on its integrated buck regulator. This buck regulator consists of an amplifier-based feedback loop, which constantly regulates the output voltage to the desired level. The output voltage is regulated by adjusting the peak inductor current which is sensed using the built-in current sensing circuit, with a resolution up to 0.01% of the nominal current. The feedback loop also regulates the output current, providing a highly accurate current control regardless of the load, power supply or temperature fluctuation.

The BD1603NUV-E2 supports both synchronous and non-synchronous operation, as well as auto-restart and blanking modes. It has an integrated ADC which measures the output current, input voltage, and output voltage, enabling comprehensive system monitoring. A comprehensive protection suite is also present, which includes a wide range of protections such as short circuit, over current and over voltage.

In summary the BD1603NUV-E2 is an ideal PMIC – LED Driver for LED lighting applications. Its wide range of operating voltage and current, integrated buck regulator feedback loop and comprehensive protection and monitoring features, make it the perfect choice for a wide range of LED lighting applications.
