RoHS: | Compliant |
The MCP19123 offers excellent regulation accuracy, in a variable output analog PWM controller with an integrated microcontroller for supervisory and management functions.
It is a mid-voltage (4.5-40V) analog-based synchronous buck PWM controller with an integrated 8-bit PIC® Microcontroller. This unique product 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. With integrated linear regulator, driver, timer, temperature sensor, and feedback network capabilities, this creates a very compact, versatile power conversion solution.
The output is adjustable on the fly, using the integrated programmable gain amplifier in the feedback path and the integrated adjustable reference voltage. In addition, the internal compensation network can also be adjusted, preserving phase margin and transient response over a wide (0.3V to 16V) output range (without external components, that range can be shifted with resistive dividers).
This device is similar to the MCP19122, but with four added pins and a serial debug interface.
