AC/DC Drivers

AC/DC controller IC for LED lighting

Included 650V MOSFET

BM521Q25F

General Description

Features

BM521Q25F is an AC/DC converter for LED lighting,

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 is 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.

Owing to the built-in start-up circuit and MOSFET with

650V withstand voltage, a compact application can be

designed easily, and the low-cost can be achieved with

the small BOM size.
