OB2603BCPA

OB2603x Secondary-side CV/CC controller with QC3.0& PE+2.0 Protocol FEATURES 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. The OB2603x automatically detects QC3.0 or PE+2.0 or BC1.2 and enables output voltage adjustments accordingly. It supports the multi-level output voltage range from 3.6V to 12V in 0.2V 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 disables the output voltage adjustment to ensure safe operation with default 5V output voltage. I-V curve is shown in Figure 1. OB2603x can achieve lower standby power consumption and fast voltage transition while TM works together with On-Bright GreenEngine based AC/DC off-line PWM ICs. The OB2603x offers comprehensive protection coverage including constant current limiting, over voltage protection at different output voltage levels and under voltage protection. OB2603x is offered in SOP8 package.  Protocol Support  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)  Automatic Identification of Protocols  Highly Integration  Secondary—Side Constant Voltage （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 Compensation  Built-in opto-coupler driver  Support 18W and 24W constant power  Low Operating Current  Wide operation voltage range from 3V to 12V.  Comprehensive protection coverage  Output over voltage protection（OVP）  Output under voltage protection（UVP）  Internal over temperature protection （OTP） co nf id en tia lt o 派 一 GENERAL DESCRIPTION APPLICATIONS O n- Br ig ht  Quick-charging AC/DC charges for cell phones, tablets and other portable devices  AC/DC Adapters for Portable Devices that Requires CV/CC control Figure1.
