... Theory of Operation The ISL6292B is based on the Intersil Patent-pending dual-mode charging technology. The dual-mode technology generates very low heat, which enables the charger to be used in space-limited applications. To take advantage of the low-heat feature, a current-limited ac/dc converter is required as the power supply to the charger. The current-limited supply has the I-V characteristics shown in Figure 1 ...
