STNRG288A:Digital controller for power conversion applications with up to 6 programmable PWM generators, 96 MHz PLL

STNRG devices are a part of the STNRG family of STMicroelectronics® digital devices designed for advanced power conversion applications.

The STNRG improves the design of the successful STLUX™ family, now integrated in a wide range of LED driver architectures, to support industrial power conversion applications such as PFC+LLC, interleaved LC DC/DC, interleaved PFC for smart power supplies as well as the full bridge for pilot line drivers for electric vehicles.
