Microchip Technology Inc. has stepped up its digitally enhanced power analogue controller line with two devices that integrate an 8bit MCU.

MCP19114 and MCP19115 support DC/DC power conversion functions including flyback, boost and SEPIC topologies. They are equipped with PWM controller and low side MOSFET driver architecture, with a mid-voltage LDO.

The controllers provide the power conversion performance typical of an analogue-based controller, with the flexibility approaching a fully-digital power conversion solution. They support configurable, high-efficiency power-conversion designs across a broad array of consumer and automotive applications and power conversion topologies.

The devices boast the speed and responsiveness expected of a high-performance analogue control loop, and the flexibility of a digital MCU. They meet automotive load dump requirements and operate across wide operating voltage ranges. They support operation up to 42V, and have integrated MOSFET drivers configured for step-up applications.

Both controllers are available for sampling and volume production in 10,000 quantities. MCP19114 is supplied in 24-lead QFN 4mmx4mm packages, while MCP19115 in 5mmx5mm packages.
