Microchip Technology

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.

The MCP19214 is a dual-channel, 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 control solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution. Combining this analog control circuit with integrated digital management features 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. The MCP19214 has independent voltage and current control, and can be configured for constant voltage or constant current operation on each of the two control loops. Alternatively, the two control loops can operate in opposite directions on the same power train, creating a bi-directional power supply. All of the key operating parameters, including the output level, are dynamically reconfigurable during operation, using the internal microcontroller core. The device features a pair of independent low side drive outputs, for controlling boost, SEPIC, Cuk or flyback topologies. This device is similar to the MCP19215, but the MCP19215 has four extra I/O pins with integrated debug support.
