Overview
| Topology | LLC Resonant Converter |
| Input voltage | 90-264 V |
| Output 1 | 50 V / 3 A |
| IC revision | 1 |
Description
This design used ON’s PFC controller NCL2801CDA and LLC controller NCL30159, with a high PF and low THD performance and NCL38046 high precision CC amplifier with Analog / PWM dimming features. Thanks to ON’s current mode PFC controller NCL2801, the reference design PFC part easy to maintain a High PF value and low THD even in very light load condition. The NCL30159 is a high performance current mode controller for half bridge resonant converters, which with an easily setting SKIP mode. This controller implements 720 V gate drivers, simplifying layout and reducing external component count.
