 Flexible design-in by means of one time programming capability for a wide range

of parameters

Description

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.
