These devices incorporate a boost PWM controller and a low-side MOSFET driver architecture, a medium-voltage LDO, and a fully functional microcontroller, all integrated into a small, high-density power package. This solution continues to offer the power conversion performance typical of an analog-based controller, while also providing the flexibility of a fully digital power conversion solution. These new analog power management devices, together with the new fully functional microcontroller, support configurable, high-efficiency power conversion designs for a wide range of consumer and automotive applications, as well as various power conversion topologies.
The MCP19114 and MCP19115 hybrid digital/analog control solutions offer the speed and responsiveness expected of a high-performance analog control loop; the flexibility of a digital microcontroller; wide operating voltage ranges; support for conventional 5, 12, and 24V rails; and the requirements of automotive load dumping. The MCP19114/19115 analog-based controllers with a digital interface provide cost-effective tunability in a high-performance power conversion solution. These devices can operate up to 42V and integrate MOSFET drivers configured for lifting applications.
Microchip also announced the MCP19114 flyback topology standalone evaluation board (ADM00578), priced at $49.99 and available now. This evaluation board features a flyback topology design with output voltages from 0V to 50V and input voltages from 8V to 14V. The entire Microchip development tool suite supports the MCP19114 and MCP19115 power controllers, including the MPLAB® X integrated development environment (IDE); the PICkit™ 3 (PG164130), priced at $44.95; the PICkit serial analyzer (DV164122), priced at $49.99; and the MPLAB XC8 compiler.
The MCP19114 is now available for sampling and volume production and is supplied in a 24-pin, 4 mm x 4 mm QFN package. The MCP19115 is also available for sampling and volume production and is supplied in a 24-pin, 5 mm x 5 mm QFN package.
