Description
The AC/DC quasi-resonant controller type LED driver IC BM520Q15F can be applied to a non-isolated application, making the designs for various types of low power converter easy. The low power consumption and high-speed start are achieved through the start-up circuit with 650V withstand voltage. Due to the quasi-resonant mode, soft switching is achieved. The EMI is also improved by the alterable operating frequency. A power supply design with a high degree of freedom can also be achieved by the external current setting resistance. A low-cost application can be achieved with the built-in MOSFET with 650V withstand voltage. It also makes the application design easy.
