ROHM BM521Q25F

Description

BM521Q25F is an AC/DC converter for LED lighting,which has a built-in MOSFET with 650V withstandvoltage. This IC can be applied to quasi-resonant typedHigh-side LED driver application, and the high currentprecision 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 tothe external current setting resistance, a power supplydesign with a high degree of freedom can be achieved.Owing to the built-in start-up circuit and MOSFET with650V withstand voltage, a compact application can bedesigned easily, and the low-cost can be achieved withthe small BOM size.
