Datasheet AC/DC Drivers AC/DC Controller IC for LED Lighting Included 650V MOSFET BM520Q25F ā—¸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.
