A digitally enhanced power analogue controller has been unveiled by Microchip.  The launch of the company’s MCP19111 is joined by the release of new MOSFETS in the form of the MCP87018, MCP87030, MCP87090 and MCP87130 ranges.  These devices are rated at 25V, so in effect the 1.8mohms, 3mohms, 9m ohms and 13mohms logic-level MOSFETs are ideally targeted at Switched-Mode-Power-Supply (SMPS) applications. 

The combination of the company’s digitally enhanced power analogue controller, which is described as a new hybrid, digital and analogue power-management device, and new family of low-Figure-of-Merit (FOM) MOSFETs, are said to support configurable, high-efficiency DC/DC power-conversion designs for a broad array of consumer and industrial applications.

This digitally enhanced power analogue family can operate across a wide voltage range of 4.5 to 32V. 

An interesting claim made by the company is that these devices are one of the world’s first hybrid, mixed-signal power-management controllers to integrate an analogue-based PWM controller with a fully functional Flash-based microcontroller. 

The company advises this integration offers the flexibility of a digital solution, with the speed, performance and resolution of an analogue-based controller.

 The MCP19111 devices are said to support operation up to 32V, and have integrated MOSFET drivers configured for synchronous, step-down applications.  When combined with the company’s expanded family of high-speed MOSFETs, these power analogue controllers drive customisable, high-efficiency power conversion.
