Onsemi NCP1339 | Demoboard NCP1339GGEVB
45W High Density Quasi-Resonant Flyback Controller Evaluation Board
Overview
| Topology | Flyback Converter |
| Input voltage | 85-265 V |
| Output 1 | 19 V / 5.1 A |
Description
The NCP1339GGEVB Evaluation Board showcases the NCP1339, a highly integrated quasi-resonant flyback controller capable of controlling rugged and high-performance off-line power supplies as required by adapter applications. With an integrated active X-cap discharge feature and power savings mode, the NCP1339 can enable no-load power consumption below 10 mW for 65 W notebook adapters. To help build rugged converters, the controller features several key protective features: an internal brown-out, a non-dissipative Over Power Protection for a constant maximum output current regardless of the input voltage, a latched over voltage protection through a dedicated pin.
