The CL330SG-G is a PMIC (power management integrated circuit) device specifically designed for LED drivers. It is a highly integrated circuit offering many dedicated features that enable an efficient and cost-effective LED driver design solution. The device combines an advanced PMIC power MOSFET and current regulator with a controller and associated circuitry into a single package.

The CL330SG-G is designed to provide an optimized solution for white LED dimming applications. The device supports external variable dimming, allowing the LED to be dimmed with external analog or PWM devices. The device is capable of driving up to 2A of LED current, and can be used for both AC and DC LED lighting designs. The device also supports LED open and short circuit protection, as well as thermal shutdown protection.

The working principle of the CL330SG-G is based on a fixed frequency current mode, step-down (buck) topology. The device is capable of working with a wide input voltage range of 4.5V to 40V, and can operate at switching frequencie up to 2MHz, allowing for the efficient use of a small external inductor and ceramic output capacitors. With the use of an external dimming signal, the output current can be varied between 10% and 80% of the full load current. The device also features a wide operating temperature range of -40C to +85C, and a high accuracy current regulation tolerance of ±1%.

The CL330SG-G is ideal for a range of LED lighting designs, including road lighting, industrial lighting, and general lighting applications. The device can also be used in automotive lighting applications, due to its wide operating temperature range and current regulation accuracy. The device also features built-in EMC protection, making it resistant to electrical disturbances from the environment. With its integrated thermal protection and open/short circuit protection, the CL330SG-G is a highly reliable, robust and cost-effective solution for LED applications.
