PCA9624PW,118 is a LED (Light Emitting Diode) driver that is classified under PMIC – LED Drivers (Power Management Integrated Circuits). This LED driver offers various features such as 18-bit PWM dimming, 0.5% PWM duty cycle accuracy, adjustable PWM frequency, 1 Amp peak current output, 5 KHz PWM dimming frequency, and adjustable dimming curves, amongst others.

As a LED driver, its primary objective is to deliver desirable current/voltage values to LED devices. This can be achieved by controlling LED through dimming. When connected to PMIC – LED Driver, the LED can be set to desired values of current/voltage, ensuring that its performance and power remain optimal against a given user’s application.

The PCA9624PW,118 LED driver is based on Texas Instruments PCA9624 family of products. It is equipped with innovative features such as high-efficiency pulse-width modulation (PWM) dimming, making it highly suitable for applications such as streetlights, decorative lighting, food and beverage lighting, signage lighting, and other industrial applications where dimming control is required.

The integrated PWM dimming control circuitry has zero-crossing based dimming control and allows dimming frequency up to 5 KHz, with 0.5% duty cycle accuracy. The adjustable PWM frequency of the device can be set to a fixed frequency or to an automatically changing frequency. In addition, it has five adjustable dimming curves that enable flexibility in terms of dimming level control.

The PCA9624PW,118 LED driver also boasts of its 1 Amp peak current output capability along with 8-bit PWM dimming resolution. It operates from a supply voltage range of 4.5 V to 30 V and can be used to drive LED strings from 6 to 18 W per chain.

Apart from the aforementioned features, the PCA9624PW,118 also has an adjustable power up/down time control, which allows the user to control the system response time. This feature can be used to protect the LED device from accidental inrush current. The device also has fully integrated fault protection circuitry that provides overtemperature, overvoltage, overcurrent, and open load detection to protect the system from any damage due to over-driving the LED.

In addition, the integrated temperature sensing allows the device to detect temperature changes and adjust the current automatically, providing additional protection and optimization for the system. It has also built-in short-circuit protection that is enabled by default, making it easier for the user to safely use the device.

The PCA9624PW,118 LED driver is available in an LGA package that is RoHS-compliant and provides superior thermal and electrical performance. This makes it suitable for applications that require superior durability and reliability. With its impressive list of features, this device can prove to be an ideal choice for any application requiring dimmable LED control and protection.
