The IDP2303 is a multi-mode PFC and LLC controller combined with a floating high side driver and a startup cell. Adigital engine provides advanced algorithms for multi-mode operation to support highest efficiency over the whole loadrange. A comprehensive and configurable protection feature set is implemented. Only a minimum of externalcomponents are required with the low pin count DSO-16 package. The integrated HV startup cell and advanced burstmode enable to achieve low stand-by power. In addition a one-time-programming (OTP) unit is integrated to provide awide set of configurable parameters that help to ease the design in phase.
