QH2213 internal integration chip 650 v power switch, the use of the original edge feedback mode, without secondary feedback circuit, also need not compensation circuit, only need few peripheral devices can realize constant current. Driven by the patent and the current way, the chip&锛�39;s working current is extremely low, without using the auxiliary transformer and power supply, further reducing peripheral components, saving the cost of the system and the volume.
QH2213 chip with high precision of current sampling circuit, LED output current accuracy within + / - 5%. Chip is the characteristic of constant current control mode, can achieve excellent linear regulation. BP3122 with multiple protection function, including LED open/short circuit protection, CS resistance short-circuit protection, under-voltage protection, chip over temperature protection, etc.
QH2213 the SOP - 8 encapsulation.
