IDP2303 Datasheet | Infineon

Product Highlights - Integrated 600V startup cell - Integrated floating driver based on coreless transformer technology - Digital multi-mode operation for higher efficiency curve - Supports low stand-by power by means of direct X-cap discharge function and advanced burst mode control - Eliminates the auxiliary power supply by means of integrated startup cell and burst mode - UART interface for munication and in-circuit configuration - Flexible design-in by means of one time programming capability for a wide range of parameters Description The IDP2303 is a multi-mode PFC and LLC controller bined with a floating high side driver and a startup cell. A digital engine provides advanced algorithms for multi-mode operation to support highest efficiency over the whole load range. A prehensive and configurable protection feature set is implemented. Only a minimum of external ponents are required with the low pin count DSO-16 package. The integrated HV startup cell and advanced burst mode enable to achieve low stand-by power. In addition a one-time-programming (OTP) unit is integrated to provide a wide set of configurable parameters that help to ease the design in phase.
