Figure 1 shows a typical dual battery charger. This circuitcan charge batteries with up to 4A and switch continuouslydown to zero load currents. This circuit takes advantageof ceramic capacitors space saving features without producing any audible noise. The high 300kHz switching frequencyallows the use of small low cost 10µH inductors. visit page.
The LTC1760 complies with the Smart Battery SystemManager (SBSM) specification V1.1. It has a very wideinput and charge output voltage range of 6V to 28V.Current and voltage accuracies of 0.2% of the reportedvalues provide precision charge capabil visit page.
