JW1782B Overview
Key Features
- JW1782B is a non-isolated, constant output current step-down LED driver with 500V MOSFET integrated
- Operating in the boundary mode makes it high efficiency and low radiation
- Patented algorithms ensure good current accuracy and excellent line/load regulations with lowest BOM cost
- JW1782B is supplied from the MOSFET drain directly, so the auxiliary winding is eliminated, which can light up the LED within 100mS
