- Product Introduction
General description
OBGZ11 is a highly integrated current mode PWMcontrol IC optimized for high performance, lowstandby power and cost effective offline flybackconverter applications.PWM switching frequency at normal operation isinternally fixed and is trimmed to tight range. At noload or light load condition, the IC operates inextended 'burst mode' to minimize switching loss.Lower standby power and higher conversionefficiency is thus achieved.VCC low startup current and low operating currentcontribute to a reliable power on startup and lowstandby design with OBGZ11.OBGZ11 offers comprehensive protectioncoverage with auto-recovery including Cycle-byCycle current limiting (OCP), over load protection(OLP), VCC under voltage lockout (UVLO), overtemperature protection (OTP), and over voltageprotection (OVP). Excellent EMI performance isachieved with On-Bright proprietary frequencyshuffling technique.The tone energy at below 25KHz is minimized inthe design and audio noise is eliminated duringoperation.OBGZ11 is offered in SOT23-6 package.
