Microchip – MCP19124/5: Digitally Enhanced Power Analog Synchronous Low Side Dual Loop PWM Controller


The MCP19124/5 is a mid-voltage (4.5V to 42V) analog-based PWM controller with an integrated 8-bit PICTM microcontroller. This unique product family 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. These products allow the development of flexible power supplies that can be configured perfectly to the target application with minimal external components.
