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