OB2362 Datasheet | On-Bright

DESCRIPTION FEATURES 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. CCM @ Heavy Load and Low Line At heavy load, the IC operates in fixed frequency(65k Hz) 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. T OB2362 offers prehensive protection coverage with auto-recovery including Cycle-by Cycle current limiting (OCP), over load protection to (OLP), and VCC under voltage lockout (UVLO). 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. fid APPLICATIONS Offline AC/DC flyback converter for n - Power Adapter - Set-Top Box Power Supplier o - Open-frame SMPS Quasi-Resonant operation @ Medium Load Green mode with valley skip @ Light Load Burst Mode @ No Load - Frequency shuffling for EMI - Extended burst mode control for improved efficiency and low standby power design - Audio noise free operation - prehensive protection coverage o VCC Under Voltage Lockout with hysteresis (UVLO) o VCC Over Voltage Protection (VCC OVP) o Cycle-by-cycle over current threshold setting for constant output power limiting over universal input voltage range o Over Load Protection (OLP) with...
