... AMC7140 is a high voltage, low dropout current regulator for maximum output current up to 700mA with OE pin. The current could be linearly adjusted through variable resister connected to I Although the absolute maximum rating of OUT pin 60V, the dropout voltage between OUT pin and GND pin should not be too large when current is sinking because of the heat dissipation capability of the package ...

... AC Voltage Input: AMC7140 could work with any kind of well-known or well-developed switch-mode power supply system. Simply cut off the internal feedback path of the power supply system and then feed the signal from AMC7140 back to the power supply system instead. Copyright © 2008 ADDtek Corp. ...

... IN(MAX) Thermal Consideration: The AMC7140 has internal power and thermal limiting circuitry designed to protect the device under overload conditions. However, maximum junction temperature ratings should not be exceeded under continuous normal load conditions. The thermal protection circuit of AMC7140 prevents the device from damage due to excessive power dissipation. When the device junction temperature rises to approximately 150° ...
