OB2603B Datasheet | On-Bright

DESCRIPTION FEATURES The OB2603x is a highly integrated secondary - Protocol Support -side constant voltage and constant current (CV/CC) controller supporting both Qualm 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 - USB BC 1.0&1.2 - Qualm 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. The high gain current sense amplifier minimizes the offset for decreasing power loss of sense resistor. 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. I-V curve is shown in Figure 1. fid OB2603x can achieve lower standby power consumption and fast voltage transition while works together with On-Bright Green Engine TM n based AC/DC off-line PWM ICs. o The OB2603x offers prehensive protection coverage including constant current limiting, over c voltage protection at different output voltage levels and under voltage protection. On-Bright OB2603x is offered in SOP8 package. （CV）and Constant Current （CC） Regualtion - Built-in Two Operational Amplifiers for Dual CV/CC control - Built-in Unplug Fast Discharging Control - Programmable Cable Drop pensation - Built-in opto-coupler driver - Support 18W and...
