No Preview Available !

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 communication 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 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-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.
Features
Multi-mode PFC
Configurable PFC gate driver
Synchronous PFC and LLC burst mode control
