±340V DC Output, 15V DC Input, Isolated Flyback Converter
This is an isolated flyback converter featuring the LT3748 chip from Analog Devices. The circuit is designed for a +/-340V DC (2 x 340V) output from a 7V to 15VDC input. The output current is up to 2 x 8mA. The board senses the isolated output voltage directly from the primary side flyback waveform during the off time of the power switch. No third winding, optocoupler, or signal transformers are required for regulation. A minimum load of approximately 2% of the maximum load is required on the output to maintain regulation.
Features
- Power Supply 7V to 15V DC @ 500mA
- Output ±340V DC
- Output Load Current 8mA + 8mA
- Soft start
- Under Voltage Lockout
- 5mm χ 4 Mounting Holes
- Screw Terminals for Easy Connection
- PCB Dimensions 78.90 x 22.23 mm
