IDP2308

Überblick

Digital multi-mode PFC and LLC combo controllers

The IDP2308 is a multi-mode PFC and LLC controller combined 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 comprehensive and configurable protection feature set is implemented. Only a minimum of external components are required with the low pin count DSO-14 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.
