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.
Summary of 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
Benefits
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 communication and in-circuit configuration
Flexible design-in by means of one time programming capability for a wide range of parameters
Potential Applications
LCD-TV 75W ~ 300W
General SMPS
