OB2734DCCP-H
DESCRIPTION
OB2734x is a highly integrated current mode PWM controller with a 650V Ga N FET integrated. It is optimized for high performance, low EMI, low standby power consumption and wide output voltage range PD adapter solutions, together with PD secondary controller, such as OB2623. The controller is as well patible with cost effective offline flyback converter applications covering a wide output range. At full load conditions, it operates in the valley switching QR mode both in the low line input and high line input. When the loading goes low, it operates in PFM mode for high power conversion efficiency. When the load is very small, the IC operates in ‘Extended Burst Mode’ to minimize the standby power loss. As a result, high conversion efficiency can be achieved in the whole loading range. In addition, at high AC line input conditions, it operates in a forced quasi-resonance (QR) valley switching mode with On-Bright proprietary technology for excellent EMI performance. OB2734x...
