PMIC - LED Drivers are a versatile and reliable power converter designed to power LEDs with a level of stability and efficiency that cannot be achieved with traditional solutions. The CPC9909N is an LED driver integrated circuit (IC) developed for automotive applications that can both dim and heat drive LED arrays with improved efficiency and thermal distribution.

The LED driver provides users with the flexibility to optimize LED performance and programmable features to meet different application requirements. The CPC9909N supports a wide range of drive currents from 1mA to 5A and features programmable thermal and dimming functions. Each channel can be independently programmed for smart dimming, as well as for temperature compensation. Furthermore, this IC can quickly detect the current consumption of each LED and modulate the output voltage and current to compensate for thermal variations.

The CPC9909N uses an internal switching frequency of up to 1MHz, and the total efficiency of the power converter can reach up to 90%. This efficient design enables designers to minimize the thermal design, improve the size and weight of their products, reduce system costs, and increase reliability.

This IC also employs a constant-current control scheme with a tight regulation loop, which is used to provide consistent current across the LED array. This design allows the user to more accurately control current levels and consequently the brightness of the LED array. The CPC9909N also features a low shutdown current of only 5uA, allowing it to be used even in applications with low standby or idle power draw.

The CPC9909N is a highly reliable power solution for driving LED arrays in a variety of automotive applications including automotive headlights, center stack, indicator, and ambient lighting applications. With its wide input voltage range of 4.5V to 28V and its high efficiency, it is an ideal solution for automotive installations. This integrated circuit can be easily configured using external pins, allowing designers to implement pre-defined schemes quickly and easily.
