Datasheet AC/DC Drivers AC/DC Controller IC for LED Lighting Included 650V MOSFET BM520Q15F General Description Features The AC/DC quasi-resonant controller type LED Quasi-resonant Switching Mode driver IC BM520Q15F can be applied to a non-isolated Built-in 650V Starter Circuit application, making the designs for various types of Built-in 650V Switching MOSFET low power converter easy. Maximum Frequency of 200kHz The low power consumption and high-speed start VCC pin: Under Voltage Protection are achieved through the start-up circuit with 650V VCC pin: Over Voltage Protection (latch) withstand voltage. SOURCE pin: Leading-Edge-Blanking Function Due to the quasi-resonant mode, soft switching is ZT pin: Trigger Mask Function achieved. The EMI is also improved by the alterable ZT pin: Over Voltage Protection (latch) operating frequency. A power supply design with a high NTC pin: Temperature Detecting Protection degree of freedom can also be achieved by the (Automatic Recovery) external current setting resistance. A low-cost application can be achieved with the built-in MOSFET with 650V withstand voltage. It also Package makes the application design easy.
