AC/DC Controller IC for LED Lighting
Included 650V MOSFET
BM520Q15F
● General 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.
