Our advantages

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China.  As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service.

Description

SL401 is a constant current driver chip with a default output current of 10mA. By using a bias resistor, the maximum output current can be set to 65mA, which can be used to drive low-power LEDs(The specific circuit can refer to Figure 6-1) At the same time, a transistor can also be connected to the output pin of SL401, and the SL401 feedback control function can be used to achieve dimming control of high-power LEDs above 65mA(The specific circuit can refer to Figure 6-2)

Features

● The output current is determined by the bias resistance and does not change with the number of LED lights in series or the change in the forward conduction voltage of the LED lights.  

● The output current is stable and will not change due to changes in the power supply voltage. It can be ignored that if the power line is too long, it will reduce the power supply voltage of SL401.

Application
● Switching mode power supplies

● DC-to-DC converters

● Motor Control, solar power
