Affected by wafer procurement costs and labor costs, the cost of LED lighting driver IC is also increasing, which has doubled the pressure on many customers. Take a look at the U6116 LED lighting driver ic U6116, which may bring new opportunities!

SUMMER

The LED lighting driver ic U6116 supports quasi-resonant step-down LED constant current, constant voltage output applications by simply shorting the SEL pin to the GND pin. It is also a high-performance primary-side controller that provides high-precision constant voltage and constant current output performance, especially for low-power offline charger applications.
