Switch-Mode Battery Charger Delivers 5A

Switch-Mode Battery Charger Delivers 5A The fast-charge controller IC3 (Figure 1) normally directs current to the battery via an external pnp transistor. In this circuit, the transistor is replaced with a 5A switching regulator (IC1) that delivers equivalent power with higher efficiency. IC1 is
