Features

• MCP19124 PWM Controller with 8 bit MCU
• Microchip MCP19124 is an analog-based PWM controller with built-in 8 bit PICR microcontroller. Combining analog and digital solutions into a single device provides products that maximize the strengths of each technology to create configurable, high-performance, and cost-effective power conversion solutions. The MCP19124 has two independent configurable external control loops that utilize a fast internal current loop for peak current mode control in a fast transient response. The unique architecture enables smooth and monotonous switching between constant voltage and constant current operation, which can be dynamically switched during operation.
