L6717 - ST Microelectronics

L6717 High-efficiency hybrid AM2r2 controller

L6717 is a hybrid CPU power supply controller embedding 2 high-current drivers for the CORE section and 1 driver for the NB section - requiring up to 2 external drivers when the CORE section works at 4 phase to optimize the application overall cost. I2C interface allows to manage offset both CORE and NB sections, switching frequency and dynamic phase managem.
