On-Bright Electronics OB2362
OB2362 is a high performance flyback adaptive ■ Power on soft start reducing MOSFET Vds multi-mode(CCM/QR) PWM controller, optimized stress to achieve high efficiency and low standby power ■ Multi-Mode Operation with effective system cost. T OB2362 offers comprehensive protection coverage with auto-recovery including Cycle-byCycle current limiting (OCP), over load protection to (OLP), and VCC under voltage lockout (UVLO).GENERAL DESCRIPTION
FEATURES
CCM @ Heavy Load and Low Line 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 , o at light load ,it operates in green mode with valley skip, and at no load the IC operates in extended a ‘burst mode’ to minimize switching loss. Lower p standby power and higher conversion efficiency is thus achieved. n VCC low startup current and low operating current contribute to a reliable power on startup and low e standby design with OB2362. It also provides the protections with latched shut l down including over temperature protection (OTP), and over voltage protection (OVP). Excellent EMI tia performance is achieved with On-Bright proprietary frequency shuffling technique. The tone energy at below 25KHz is minimized in n the design and audio noise is eliminated during e operation. OB2362 is offered in SOT23-6 package. fidAPPLICATIONS
