Details, datasheet, quote on part number: MCP19122
TitlePower analog controller converts, measures, and manages power
DescriptionThe MCP19122 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 PICŪ 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. Combining these solution types creates a new family of devices that maximizes the strengths of each technology to create a more cost-effective, configurable, high-performance power conversion solution. With integrated linear regulator, driver, timer, temperature sensor, and feedback network capabilities, this creates a very compact, versatile power conversion solution.
