Microchip Technology MCP19122 & MCP19123 Hybrid Controllers
Microchip Technology MCP19122 and MCP19123 Hybrid Controllers offer excellent regulation accuracy, in a variable output analog PWM controller with an integrated microcontroller for supervisory and management functions. The MCP19122 and MCP19123 are mid-voltage (4.5V to 40V) analog-based synchronous buck PWM controllers with an integrated 8-bit PIC® Microcontroller. This 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.
