BM520Q25F
●Description BM520Q25F is an AC/DC converter which has a built-in MOSFET with 650V withstand voltage. This IC can be applied to quasi-resonant typed High-side LED driver application, and the high current precision and Low EMI noise can be achieved. Moreover, owing to the built-in PFC (Power Factor Correction) converter, the harmonics can be improved. Owing to the start-up circuit with 650V withstand voltage, the low power consumption is achieved. And owing to the external current setting resistance, a power supply design with a high degree of freedom can be achieved. With the built-in MOSFET with 650V withstand voltage, a low-cost application can be achieved, and it makes the application design easily. ●Features Quasi-resonant switching mode + PFC circuit Built-in 650V starter circuit Built-in 650V switching MOSFET Maximum frequency 200kHz VCC pin: under voltage protection VCC pin: over voltage protection (latch) SOURCE pin: Leading-Edge-Blanking function LED over current detection function ZT pin: trigger mask function ZT pin: over voltage protection (latch) FET over current protection function LED current AC compensation function
