The PCA9685 is a 16-channel I2C-bus controlled LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlight. Each LED output has individual 12-bit resolution (4096 steps) PWM controller with a fixed frequency.
The 2SK3562, 2SK-3562, K3562, 3562 is a Silicon N-Channel Field Effect Transistor. This is an N-Channel MOSFET type of field effect transistor (FET) that is TO-220F Package as the conducting channel to control the flow of current.
The device can effectively suppress the surge current, and its resistance and power consumption can be greatly reduced after that through the continuous effect of the current so as not to affect the normal work current. Therefore the Power NTC thermistor
The BP2326A is a high precision non-isolated buck driver with active PFC, specially designed for universal input offline constant current LED lighting. The driver with on-chip PFC circuit achieves high power factor and low THD.
