Overview
CONSONANCE PFM Step-up Battery Charger Controller IC CN3300 General 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 components.
The CN3300 enter charging mode on power up, the external N-channel MOSFET is turned on, when the inductor current rises to the upper limit, the N-channel MOSFET is turned off, then inductor current begins to fall, the energy stored in inductor is transferred to the battery.
