Overview
OB2633 is a highly integrated QuasiResonant(QR) controller with adaptive multi - mode regulation, optimized for high performance, low EMI, low standby power consumption and wide output voltage range Quick Charger(QC) solutions, together with secondary - side controllers, such as OB200x and OB2603x supporting Qualcomm Quick Charge QC3.0 protocol. The controller is as well compatible with cost effective offline flyback converter applications covering a wide output range. The ‘Extended burst mode’ control greatly reduces the standby power consumption and helps the design easily to meet the international power conservation requirements.
Applications
- Offline AC/DC flyback converter for Quick - charging AC/DC charges
- AC/DC Adapters with wide output range
Key features
- Very wide range of supply voltage
- 75KHz maximum clamping frequency in QR mode @ Full Load in high line voltage
- 55KHz minimum clamping frequency in CCM mode @ Heavy Load in low line voltage
- Valley switching operation @ Green mode
- Burst Mode @ Light Load & No Load
- Power on soft start reducing MOSFET Vds stress
- Extended burst mode control for improved efficiency and low standby power
- Soft Start for elimination output over shoot
- Adaptive loop gain compensation with Iovp current detection
- Adaptive Frequency shuffling for EMI
- Low operating current at no/light load
- Audio noise free operation
- Comprehensive auto - recovery protection
- VDD under voltage lockout with hysteresis (UVLO)
- Cycle - by - cycle over current protection (OCP)
- Overload protection (OLP)
- Over temperature protection (OTP)
- VDD over voltage protection
- Output over voltage protection
- Output short protection (SCP)
- Output under voltage protection (UVP)
- Output diode short protection
