The HV9910CNG-G-M934 is a PWM controller for LED applications which is designed to provide excellent levels of current regulation and system efficiency in driving highbrightness LEDs. It features a 1.8/2.5/3.3/4.3V integrated startup voltage, allowing for higher or lower output currents with a single device, as well as an adjustable LED current sinking of up to 600mA. It also offers an adjustable LED current sink of up to 2A, depending on the design.

The HV9910CNG-G-M934 can be used for various LED applications such as lighting, backlighting, signage and automotive applications. It is available in a small 8-pin surface mount package with a maximum power dissipation of 200mW and a typical operating current of 70mA.

The HV9910CNG-G-M934 is a single-channel constant current sink PWM controller, which implements a single-ended PWM signal. It operates using an input voltage of 8-17V DC, and it supports a wide range of PWM frequencies (up to 500kHz). It also features adjustable frequency, dead time and peak current limit. The HV9910CNG-G-M934 is capable of outputting a linear current up to 600mA.

The HV9910CNG-G-M934 utilizes an advanced Pulse Width Modulation (PWM) technique to achieve a smooth and efficient LED current regulation. The LED is constantly driven with a very narrow and stable LED current, providing precise control of LED luminance and uniformity. The device supplies precise LED protection by preventing LED current output transistor over-temperature as a result of over-current in the LED string. Furthermore, it incorporates a programmable timer to protect against damage to the load in the event of a short-circuit or open-load condition.

In addition, the HV9910CNG-G-M934 features adjustable slew rate control, an adjustable current slew rate, adjustable frequency and dead time, adjustable peak current limit, and a PWM frequency control of up to 500kHz. It also offers an adjustable startup voltage of 1.8/2.5/3.3/4.3V for higher or lower output currents. Finally, it provides high-efficiency switching, resulting in minimum power loss during operation.

In summary, the HV9910CNG-G-M934 is a PWM controller for LED applications which is designed to provide excellent levels of current regulation and system efficiency in driving high-brightness LEDs. It can be used for various LED applications such as lighting, backlighting, signage and automotive applications. Moreover, it implements an advanced Pulse Width Modulation (PWM) technique to achieve a smooth and efficient LED current regulation, and offers adjustable frequency, dead time, peak current limit and slew rate. The device is available in a small 8-pin surface mount package, and has a maximum power dissipation of 200mW and a typical operating current of 70mA.
