On-Bright Electronics OB2362D
OB2362D is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. When the loading goes low, it operates in Green mode with valley switching for high power conversion efficiency. When the load is very small, the IC operates in ‘Extended Burst Mode’ to minimize the standby power loss.GENERAL DESCRIPTION
At full loading, the IC operates in fixed frequency (65KHz) mode. As a result, high conversion efficiency can be achieved in the whole loading range. VCC low startup current and low operating current contribute to a reliable power on startup and low standby design with OB2362D. OB2362D offers comprehensive protection coverage with auto-recovery including Cycle-byCycle current limiting (OCP), over load protection (OLP), VCC under voltage lockout (UVLO), over temperature protection (OTP), and over voltage protection (OVP). Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique. The tone energy at below 23KHz is minimized in the design and audio noise is eliminated during operation. OB2362D is offered in SOT23-6 package.APPLICATIONS
