Full-bridge Type, Half-bridge Type
[Feature: Full-bridge/Half-bridge Type]
• Pch/Nch drive
• A large current device can drive multi tubes, thus the needed parts count can be reduced.
[Feature: Half-bridge Type (High voltage input)]
• A highly effi ective system can be achived by using a high side driver, whitch can make the inverter cicuit to be operated at a PFC
voltage level.
MOSFET should be Nch type and withstand a high voltage.
Separately-excitation Package Polarity Type No.

Self-excitation Type (collector resonance)
[Feature]
• Multi tubes can be driven by using a power device with large current capacity.
→
also, the number of inverter circuits and used parts can be reduced.
• 4 to 8 tubes can be driven by circuit.
• Best choice for low-cost sets.
Self-excitation Package Type No.
