PMIC - LED Drivers

NCV7681APWR2G is a DC-DC converter controller with integrated high-current power MOSFETs designed for a broad range of LED applications such as automotive headlights, auxiliary lights, and backlight arrays. This device can drive up to 4 LEDs in parallel, consuming up to 40W total, with a maximum of 7.2A per LED string. The device includes active FETs that can be used to short LED channel pins if the monitored LED light is not detected, enabling smooth dimming control of the LEDs.

The NCV7681APWR2G has an adjustable frequency range of 300 kHz to 2.2 MHz, allowing the use of smaller and less expensive inductors as well as providing location flexibility on a crowded circuit board. Voltage step-up or step-down modes can be selected to accommodate varying forward voltage needs across different applications and all relevant input and output voltages are triple-cell, allowing the device to operate from a wide range of battery voltages.

The NCV7681APWR2G provides a high efficiency power stage design that features a full bridge of integrated PMOS FETs (across the inductor), combined with dedicated control circuitry, results in higher efficiency than compared to discrete external power MOSFET solutions.

The device also integrates protection features such as a rugged internal over-temperature circuitry, wide voltage clamping range, switching frequency foldback, short-circuit protection, active short with diode emulation and robust external fault handling capability. In addition, the NCV7681APWR2G has a high integration level that both reduces the external component count and cost, while making the solution more space efficient.

The NCV7681APWR2G is an ideal controller solution for space tight applications requiring large number of high brightness LEDs.

The working principle of the NCV7681APWR2G is in line with that of other LED drivers – it takes in an input DC voltage and uses a step-up or step-down converter depending on the application to drive the LEDs. The device features a high-current power MOSFET driver circuit, which is designed to drive the LED current to approximately 7.2A. The device also has an extensive protection suite which helps protect the device from excessive temperatures, clamping, short-circuits and active shorts.

Apart from its use in automotive headlights, auxiliary lights and backlight arrays, the NCV7681APWR2G can be used across a wide range of applications such as display lights, emergency lights, emergency vehicle lights, signage, stage and theater lighting and decorative lighting. Moreover, due to its robust protection features, it is suitable for challenging automotive environments.

In conclusion, the NCV7681APWR2G from ON Semiconductor offers excellent performance, easy setup and wide range of features, making it an ideal choice for LED driver applications in space-constrained environments that require large numbers of high-brightness LEDs.
