Non-isolated dimmable 5W LED Driver Circuit

This circuit is used in the general range of AC input voltage (85 VAC to 265 VAC, 47 Hz to 63 Hz) to work, but in 0 VAC to 300 VAC input voltage range will not cause damage. This can improve the reliability of field application to extend the line voltage sag and surge conditions of life. LinkSwitch-PL-based design provides high power factor (> 0.9), to help meet the requirements of all existing international standards, will enable a single design over the globe.

The shape of the power of choice to meet the standard pear-shaped (A19) LED replacement light requirements. Non-isolated output, requiring mechanical enclosure design to the power output and LED load and user isolation.
