Features:

• Output Power: 80W max
• Switching regulator power IC fabricated using Sanyo’s original IMST ( Insulated Metal Substrate Technology)
• One IC can make up a selectors voltage regulator applicable to line voltages from 85VAC to 280VAC
• The 7300 series are pin-compatible
• The oscillator circuit is of the self-oscillating type.
• Functional trimming permits the output voltage to be set with high accuracy ( /-1V)
• No feedback from the secondary to the primary side provides the following features
• Simple circuit with a minimum number of parts required, permitting an inexpensive and reliable voltage regulator to be realized
• Since it is unnecessary to use an insulating element, such as a photocoupler, in the feedback channel, it is easy to meet the requirements of safety standards.
