Microchip, Buck Boost Controller 40V QFN 28-Pin

The MCP19123 offers excellent regulation accuracy, in a variable output analog PWM controller with an integrated microcontroller for supervisory and management functions. It is a mid-voltage (4.5-40V) analog-based synchronous buck PWM controller with an integrated 8-bit PIC® Microcontroller. This unique product combines the performance of a high-speed analog solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution.
