On-Bright Electronics OB2603A
The OB2603x is a highly integrated secondary Protocol Support -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. The high gain current sense amplifier minimizes the offset for decreasing power loss of sense resistor.| Part No. | OB2603A |

GENERAL DESCRIPTION
FEATURES
The OB2603x is a highly integrated secondary● Protocol Support -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. Two
● USB BC 1.0&1.2
● Qualcomm Quick Charge 2.0 & 3.0 (QC2.0 & QC3.0)
● Media Tek Pump Express 1.0& 2.0 (PE+1.0 & PE+2.0) operational amplifiers are built in for voltage loop
● Automatic Identification of Protocols (CV) and current loop (CC) regulation with
● Highly Integration programmable voltage reference to provide
● Secondary—Side Constant Voltage adaptive CV and CC in high precision. to The OB2603x automatically detects QC3.0 or PE+2.0 or BC1.2 and enables output voltage adjustments accordingly. It supports the multi-level l output voltage range from 3.6V to 12V in 0.2V tia increments for QC3.0 protocol. And it provides the output voltage from 5V to 9V in 0.5V increments and 12V voltage for MTK PE+2.0 protocol. If quick charge protocol is not detected, the OB2603x n disables the output voltage adjustment to ensure e safe operation with default 5V output voltage.
