an8083s Panasonic Corporation of North America, an8083s Datasheet - Page 5

• Manufacturer Part Number: an8083s
• Description: Low Voltage Operation Ic For Dc-dc Converter
• Manufacturer: Panasonic Corporation of North America

• Miscellaneous
1. Method for making output voltage variable
2. Method for making decreased voltage detection variable
3. Reset output
• Chopper type application
ICs for CD/CD-ROM Player
When the output voltage is made variable, detection voltage changes.
However, take care that an external resistance causes different temperature characteristics.
