CN3300 Description
The CN3300 is a step up battery charger controller IC which operates from an input voltage of 4V to 28V. The CN3300 includes on-chip reference voltage, +5V voltage regulator, inductor current sensing, battery voltage monitoring and N-channel MOSSFET driving blocks, etc, which makes the CN3300 easy to be used with few external ponents. The CN3300 enter charging mode on power up, the external N-channel MOSFET is...
