Data Sheet
AP4301
The AP4301 is a monolithic IC specifically designed · Input offset voltage: 0.5mV
to control the output current and voltage levels of · Supply current: 250µA per Op-Amp at 5.0V sup-
switch mode battery chargers and power supplies.

Note: Stresses greater than those listed under "Absolute Maximum Ratings " may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated under "Recommended Operation Ratings " is not implied. Exposure to "Absolute Maximum Rat-
ings " for extended periods may affect device reliability.
