raybet雷电竞首页电源类芯片OB2601X/03XOB2603x
The OB2603x is a highly integrated secondary -side constant voltage and constant current (CV/CC) controller supporting both Qualcomm Quick Charge QC3.0 protocol and Media Tek Pump Express Plus 2.0 PE+2.0 protocol. It is used in application that requires constant voltage (CV) and constant current (CC) regulation. Two operational amplifiers are built in for voltage loop (CV) and current loop (CC) regulation with programmable voltage reference to provide adaptive CV and CC in high precision. The high gain current sense amplifier minimizes the offset for decreasing power loss of sense resistor.
