SC667ULTRT

The SC667ULTRT is a highly efficient, cost effective, power supply module specifically designed to support LED lighting applications. It can be used as a stand-alone driver or in combination with a lighting controller. The SC667ULTRT is suitable for both indoor and outdoor environments and is designed to provide high-efficiency, high-reliability and low-cost solutions to power LED lighting.

The SC667ULTRT application field is Power Management IC (PMIC) - LED Drivers. This power supply module consists of two main components: a primary switching regulator and a secondary switching controller. The primary switching regulator takes in an input voltage and provides a constant regulated power supply for the LED. The secondary switching controller provides gate drive signals to the LED to control its brightness.

The SC667ULTRT has a wide input voltage range and is capable of operating from 0.5V up to 36V in both single-ended and differential voltage topologies. This makes it suitable for a variety of LED light sources, from low-voltage single-LEDs to high-voltage array-LEDs. The power supply also features built-in protection features to ensure the safety of the device, as well as low-voltage and overload protection.

The working principle of the SC667ULTRT is based on the switching of a semiconductor switch, a voltage deriver, and a capacitor. The semiconductor switch is activated by the voltage derived from the voltage control circuit which is generated by the control signal from the lighting controller. The capacitor forms a low-pass filter which is used to reduce the voltage ripple.

The switching frequency of the SC667ULTRT is adjustable between 500kHz and 2MHz, allowing for a wide range of LED lighting applications. It also has a built-in switching frequency of 500kHz and a 1MHz fixed-frequency mode which can be used when the load is static.

The SC667ULTRT provides high-efficiency by incorporating advanced power conversion techniques and the latest process technology. It also allows for the use of multiple switching frequencies, which can reduce switching losses, and is capable of providing a high power density.

The SC667ULTRT is an ideal choice for low-cost lighting applications, as it combines high efficiency, cost-effectiveness, and reliable performance. It is ideal for use in both indoor and outdoor environments and provides a high power density, allowing for higher-performance LED lighting solutions.
