Microchip Technology's MCP19123 power supply analog controller is a medium voltage (4.5 V to 40 V) analog synchronous buck PWM controller with an integrated 8-bit PIC microcontroller. This unique product combines the performance of high-speed analog solutions with the configurability and communication interfaces of digital solutions. The controller provides a variable output analog PWM controller with excellent regulation accuracy, high efficiency and fast transient response. Integrated microcontroller control monitoring and management functions.
Combining these solution types, you can create a series of devices to maximize the advantages of each technology, thus creating a more cost-effective, configurable, high-performance power conversion solution. These devices are supported by Microchip's suite of programming and development tools, including the MPLAB X Integrated Development Environment (IDE) and the MPLAB XC8 compiler. The integration of linear regulators, drivers, timers, temperature sensors and feedback networks creates a very compact, versatile power conversion solution.
The MCP19123 buck controller provides many unique functions, including a programmable differential input amplifier, to optimize performance and minimize system voltage errors. This configurability allows a wide range of output voltages, typically seen in USB power supply and battery charger applications. The device can be synchronized to the external clock and voltage reference, or provide the internal system clock and reference to other devices for synchronization.
In servers or communication devices, this allows seamless power up and accurate tracking of power consumption across the board. For high power applications, multiple outputs can be operated in parallel to provide system redundancy to improve system reliability. Combined with on-board programmable diagnosis and fault detection capabilities, the MCP19122/3 is unmatched in the industry. The MCP19122/3 is an ideal choice for high-performance intelligent power applications.
