Description: High Performance Quasi-Resonant PWM Cont roller OB2201 Product Specification GENERAL DESCRIPTION OB2201 is a high pe rformance flyback QuasiResonant (QR) co ntroller optimized to achieve high effi ciency in the universal input range and full loading range with effective syst em cost. At full loading, the IC operat es 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 unive rsal input range at full loading can be achieved. At normal load condition, it operates in QR mode. To minimize switc hing loss, the maximum switching freque ncy in QR mode is internally limited to 90 KHz. When the loading goes low,
