OB2608

GENERAL DESCRIPTION

        The OB2608 is a highly integrated secondary-side constant voltage and constant current (CV/CC) controller supporting HUAWEI SCP protocol and Qualcomm Quick Charge 2.0 (QC2.0) protocol. It is designed for use in applications that require Constant Voltage (CV) and Constant Current (CC) regulation. Two operational amplifiers are built in for voltage loop and current loop regulation with programmable voltage references according to protocols. The high gain current sense amplifiers minimize the offset for decreasing power loss of sense resistor.
