Support QH3118 is a TRIAC dimmer LED constant current control core
Slice. Apply input voltage range isolated Flyback LED constant current
Power supply.
QH3118 operates in discontinuous inductor current mode, using primary sidefeedback model
No secondary feedback circuit, can be realized without compensation circuit
Constant current, greatly saves system cost and size. Chip
Eli&锛�39;s constant current control mode, excellent rate linear adjustment can beachieved and
Load regulation.
QH3118 integrated circuit thyristor dimmer control, external
Requires only minimal components to achieve dimming in conjunction withchip.
Wide dimming range, without blinking.
QH3118 current with high precision sampling circuit
LED output current accuracy is within 卤 3%.
QH3118 has multiple protection features, including LED open circuitprotection, LED
Short circuit protection, chip over-temperature protection, overvoltageprotection, undervoltage protection,
FB short-circuit protection.
QH3118 in the SOP-8 package.
