Device Overview

Summary

The MCP19125 is a mid-voltage (4.5-42V) 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. In addition, these devices can be programmed to dynamically respond to measurements or events within the system, dynamically tailoring the operation to the environment, or intelligently responding to faults for robust operation.
This device contains two independent outer control loops, which can be configured with separate feedback networks, and separate references. The analog voltage loop can be set to control a constant voltage, or the analog current loop can be used to set a constant current on the output. Regardless of which outer loop is being used, both outer loops take advantage of a faster, inner current loop for peak current mode control with fast transient response. With this unique architecture, switching between constant-voltage and constant-current operation is smooth and monotonic; it can be done dynamically during operation without glitching or undesirable transient effects.
