High Performance Quasi-Resonant PWM Controller OB2201 Product Specification GENERAL DESCRIPTION OB2201 is a high performance flyback QuasiResonant (QR) controller optimized to achieve high efficiency in the universal input range and full loading range with effective system cost. At full loading, the IC operates in fix frequency (52KHz) CCM mode in the low line input range and operates in QR mode in high line input range. In this way, high efficiency in the universal input range at full loadin
