AC/DC controller IC for LED lighting

BD521GOFJ

General Description

Features

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.

 Quasi-resonant Switching Mode + PFC Circuit

 Non-isolated Application

 Maximum Frequency 300kHz

 VCC Pin: Under Voltage Protection

 VCC Pin: Over Voltage Protection (Latch)

 CS Pin: Leading-Edge-Blanking Function

 CS Pin: OPEN Protection Function

 LED Over Current Detection Function

Package

W(Typ) x D(Typ) x H(Max)

4.90mm x 6.00mm x 1.65mm

Owing to the external current setting resistance, a

power supply design with a high degree of freedom

can be achieved.

SOP-J8
