LED drivers are essential components in lighting systems, as they provide the necessary power and control to drive LEDs. The PAM2861CBR IC is a wide input voltage LED driver for LED lighting systems that provides two dimming control modes. It was designed for solid-state luminaires in permanent mains installations, such as those in public spaces, commercial buildings and other professional applications. The device has a wide operating range of 6.5V–42V, making it ideal for a wide range of input systems. It is capable of delivering up to 4A of current with a minimum 0.2V output voltage drop.

The device features an adjustable switching frequency of either 1kHz or 2kHz and provides two different dimming control modes. In the standard dimming mode, the dimming control voltage is varied from 0V up to 1V in order to provide an adjustable dimming range from 0% to 100%. Alternatively, the pulse width modulation (PWM) dimming mode provides a wide range of dimming levels from 0% to 100%, depending on the PWM frequency, duty cycle and resolution.

The PAM2861CBR IC also features a power-on reset circuit, which helps to initialize the output of the device for optimal performance and functionality. Additionally, the IC has an adjustable peak current control function which helps to protect IC against excessive current and thermal derating. The device also features built-in protection features including open LED detection, short LED detection, over temperature protection and current limiting.

The PAM2861CBR IC can be used in a variety of LED lighting systems, including LED spotlights, LED strips, LED lamps and other professional lighting applications. With its wide input voltage range, adjustable dimming modes, peak current control and various protection features, the PAM2861CBR IC is an ideal solution for LED lighting systems that require high performance and reliable operation.
