Beschreibung

BD521GOFJ is an AC/DC converter for LED lighting.
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 harmonic is improved.
By choosing the external MOSFET, the LED drivers
for from low power to high power can be achieved. So
that, it can be widely used on from the low power
lighting such as spotlight to the high power lighting
such as base light.
Owing to the external current setting resistance, a
power supply design with a high degree of freedom
can be achieved.
