Expanding the company's digitally enhanced power analogue controller portfolio, Microchip Technology has announced the MCP19114 and MCP19115. These devices introduce a step-up PWM-controller and low-side MOSFET driver architecture, with a mid-voltage LDO and fully-functional microcontroller all integrated into a small, high-density power package.

This solution continues to offer the power conversion performance typical of an analogue-based controller, with the flexibility approaching that of a fully-digital power conversion solution. These new analogue power-management devices, in combination with the fully-functional microcontroller, support configurable, high-efficiency power-conversion designs across a broad array of consumer and automotive applications and power conversion topologies.

The MCP19114 and MCP19115 hybrid digital-analogue control solutions offer the speed and responsiveness expected of a high-performance analogue control loop; the flexibility expected of a digital MCU; operate across wide operating voltage ranges; support conventional 5, 12, and 24V rails; and meet automotive load-dump requirements. The MCP19114/19115 analogue-based controllers with digital interface, offer cost-efficient adjustability in a high-performance power conversion solution. These devices support operation up to 42V, and have integrated MOSFET drivers configured for step-up applications.

Microchip also announces the MCP19114 Flyback Standalone Evaluation Board (ADM00578) priced at $49.99 (USD). This evaluation board is offered with a flyback design supporting 0-50V output from an 8-14V input. Microchip’s full suite of development tools supports the MCP19114 and MCP19115 power controllers, including the MPLAB X integrated development environment; the PICkit 3 (PG164130) priced at $44.95 (USD); PICkit Serial Analyzer (DV164122) priced at $49.99 (USD), and the MPLAB XC8 Compiler.

The MCP19114 is available now for sampling and volume production in a 24-lead QFN 4x4mm package. The MCP19115 is available now for sampling and volume production in a 24-lead QFN 5x5mm package.
