OB2362

On-bright confidential to Tenpao OB2362 Adaptive Multi-Mode PWM Controller GENERAL DESCRIPTION OB2362 is a high performance flyback adaptive multi-mode(CCM/QR) PWM controller, optimized to achieve high efficiency and low standby power with effective system cost. At heavy load, the IC operates in fixed frequency(65kHz) CCM mode in the low line input voltage. At medium load, it operates in QR mode , at light load ,it operates in green mode with valley skip, and at no load the IC operates in extended ‘burst mode’ to minimize switching loss. Lower standby power and higher conversion efficiency is thus achieved. VCC low startup current and low operating current contribute to a reliable power on startup and low standby design with OB2362. OB2362 offers comprehensive protection coverage with auto-recovery including Cycle-byCycle current limiting (OCP), over load protection (OLP), and VCC under voltage lockout (UVLO). It also provides the protections with latched shut down including over...
