Summary:
The flyback converter uses a device in the TinySwitch-III family (U2, TNY279PN) to deliver up to 1.8 A of load current to six high-brightness lumen LEDs (LXHL series).
design feature
- Very high efficiency: >82%
- Small component count: only 40 components
- Meets EN55022B for conducted EMI requirements without the need for common mode inductors
- The valley filling circuit enables the power supply to meet the IEC61000-3-2 THD limit
- ON/OFF control suppresses higher power frequency ripple voltage caused by valley filling (THD correction) circuit

Semiconductor Stud Devices are mainly used for rectifying and switching
By using the unidirectional conductivity of the diode, alternating direction alternating current can be transformed into pulse direct current in a single direction.
Applications for Medium power switching and DC power supplies.
