CN3305 - PFM Step-up Multi-cell Battery Charger

Key Features

  • CN3305 is a PFM mode step-up battery charge management IC with operating voltage range between 2.7V to 6.5V. It is specially designed for multi-cell lithium-ion, LiFePO4 and Lead Acid battery charge management with fewer external components. CN3305 adopts constant current and quasi-constant voltage(Quasi-CVTM) mode to charge battery. On power up, CN3305 enters charging mode, the external N-channel MOSFET is turned on, inductor current rises. When inductor current reaches upper threshold, the N.

CONSONANCE PFM Step-up Multi-cell Battery Charger IC CN3305 General Description： Features： CN3305 is a PFM mode step-up battery charge management IC with operating voltage range between 2.7V to 6.5V. It is specially designed for multi-cell lithium-ion, LiFePO4 and Lead Acid battery charge management with fewer external components. CN3305 adopts constant current and quasi-constant voltage(Quasi-CVTM) mode to charge battery. On power up, CN3305 enters charging mode, the external N-channel MOSFET is turned on, inductor current rises. When inductor current reaches upper threshold, the N-channel MOSFET is turned off, inductor is discharged, the energy stored in inductor is transferred to battery.
