How to Minimize Power Dissipation in Li+ Linear Chargers


要約: Techniques are described for minimizing power dissipation in linear battery chargers. Beginning with a stable wall-cube switching power source, methods are described to limit the dissipation in the linear charging circuit. Circuits are provided, calculations are shown, heat sinking for the PMOS pass transistor is discussed, and suitable pass transistors are suggested.
