Microchip MCP19123T-E/MQ, 1 Buck Boost Switching, Buck Boost Controller 35A, 0.3 → 16 V, 1.6 MHz 28-Pin, QFN

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.
