Summary of New Digitally Enhanced Power Analog Controllers From Microchip
Microchip Technology introduced the MCP19118 and MCP19119, industry-first PMBus-compatible controllers featuring 40V operation. These Digitally Enhanced Power Analog (DEPA) devices offer analog PWM control for DC-DC synchronous buck converters while integrating an 8-bit PIC MCU core for programmable firmware configuration. This combination enables rapid development of compact power-conversion circuits with both simple analog loops and digital flexibility.
Parts used in the MCP19118/9 Project:
- MCP19118 controller
- MCP19119 controller
- DC-DC synchronous buck converter
- PMBus communication interface
- 8-bit PIC MCU core
MCP19118/9 Provide Simple Analog PWM Control and Configurable MCU in Compact Circuit Solution; Industry’s First PMBus Compatible Controller With Up to 40V Operation.
Microchip Technology Inc. announced its latest Digitally Enhanced Power Analog (DEPA) controllers—the MCP19118 and MCP19119 (MCP19118/9). They provide simple yet effective analog PWM control for DC-DC synchronous buck converters up to 40V, with the configurability of a digital MCU. And they are the industry’s first devices to combine 40V operation and PMBus communication interfaces. These features enable quick power-conversion circuit development with an analog control loop that is programmable in the integrated 8-bit PIC MCU core’s firmware.
