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.

Features
 Multi-mode PFC
 Configurable PFC gate driver
 Synchronous PFC and LLC burst mode control
 Configurable non-linear LLC VCO curve
 Configurable soft-start
 VAC input voltage sensing and X cap discharge via HV pin

Applications
 LCD-TV 75W ~ 300W
 Generarl SMPS
