Bp2861ck drives the i. C. B. P. S. Brand without vcc

Bp2861xk is a pressure-relief led constant flow drive chip. The chip works in the critical current continuous mode of the electrons and applies to non-separated led constant current power sources that input voltage in a full range of 85vac ~265vac. The internal integration of the bp2861xk chip into a 500v power switch, the use of grid-regressive magnetic detection and high-pressure jfet power supply technology, the non-use of vcc capacitor and the activation of electrical resistance, made the peripherals simpler and cost- and volume-saving。
