Summary:
The isolated flyback converter is designed around the PKS606PN (U1) of the PeakSwitch product line. Choosing a P-packaged device (8-pin DIP) minimizes the cost and size of the heat sink for peak power output.
design feature
- The peak output power is greater than 2 times the continuous output power, and the amplifier has no distortion.
- Universal input voltage range for worldwide use
- High efficiency (>79%) across the entire input range
- Meet EN55022 B Conducted EMI Limit
- Auto-restart feature allows long-term short-circuit output
- Thermal shutdown power supply and amplifier
