... Theory of Operation The ISL6297 is based on the Intersil Patent-pending dual- mode charging technology. This allows the ISL6297 to function as a traditional linear charger when powered with a voltage-source adapter. However, when powered with a current-limited adapter, the charger minimizes the thermal dissipation commonly seen in traditional linear chargers. ...
