NCV3066PG is a high-performance power management integrated circuit (PMIC) designed for driving LED displays. It is part of the widely used NXP power management integrated circuit (PMIC) family and is intended for use in high speed optocouplers and LED backlighting applications. NCV3066PG provides high-efficiency, high-voltage, low-ripple control of LED current through its high-voltage MOSFET array.

The NCV3066PG offers an integrated PWM controller and two independent channels. Each channel can drive up to 15 LEDs up to 25V. It provides wide input voltage range and high efficiency up to 95 %. It also offers programmable frequency and dimming to provide excellent dimming control. The NCV3066PG is capable of driving high current LED loads, up to 1A. It also offers thermal protection and undervoltage lockout protection.

NCV3066PG application fields include displays, LED backlighting and illumination, cold cathode lighting, power supplies and other power management applications. Its working principle is based on controlling the current of the LEDs via the Output Channel MOSFET array. This is done by setting the Pulse Width Modulation (PWM) and gradually fading the LEDs’ current to the desired level, which results in a dimming effect. The PWM can be connected to an external microcontroller for dimming or flashing of the LEDs. DC/DC converter, isolated or non-isolated buck power conversion can also be used to control the LEDs current.

NCV3066PG offers different features for different applications. For example, for LED backlighting it offers short-circuit protection, open-circuit protection, over-voltage and over-temperature protection. For display applications, it offers protection against events that could damage the LEDs such as over-current, over-temperature and reverse current flow. It also offers current steering and current sense functionality, which provides improved regulation and better current control.

NCV3066PG is a versatile, high performance PMIC designed to meet the demands of many LED applications. It offers high-power efficiency, wide input voltage range and exceptional current control capabilities. By providing both integrated PWM and multiple channels, it enables effective and efficient control over LED current. In addition, its features, protection and dimming capabilities make it a ideal solution for driving high-brightness LED displays, backlighting and illumination.
