37 / 41 page  AN4130 Extensions and modifications Doc ID 023315 Rev 1 37/41 Figure 42. Transformer specification for 9-LED load 7.2 Higher line voltage This is almost a wide-range design, dimmable at 90 V-130 V, and operable from 90 V to 305 V. The only thing preventing this is the voltage rating of capacitors and the output diode. The HVLED815PF’s internal FET is rated for 800 V, a good design margin for European 230 V lines and US 277 V lighting circuits. The design is not sensitive to input frequency. AC injection divider (R3-R4) is adjusted, reasonable harmonic distortion (THD) performance can be expected from 180 V to 305 V. At higher input voltage the surge limiting resistor R1 should be coordinated with the single- cycle surge rating of the input bridge. Triac dimming at higher input voltage requires redesign of the input filter. |
