GENERAL DESCRIPTION
PWM switching frequency at normal operation is internally fixed and is trimmed to tight range. At no load or light load condition, the IC operates in extended burst mode to minimize switching loss, which can achieve less than 75mW standby. VDD low startup current and low operating current contribute to a reliable power on startup and low standby design with DP2269. Excellent EMI performance is achieved with frequency shuffling and soft totem pole gate drive The tone energy at below 20KHz is minimized in the design and audio noise is eliminated during operation. DP2269 is offered in SOP8 package. Product SpecificationFEATURES
