These latest 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 analog-based controller, with the flexibility approaching a fully-digital power conversion solution.

These new analog power-management devices, in combination with the fully-functional microcontroller (MCU), 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-analog control solutions offer the speed and responsiveness expected of a high-performance analog control loop; the flexibility expected of a digital MCU; operate across wide operating voltage ranges; support conventional 5, 12, and 24 V rails; and meet automotive load dump requirements.

The MCP19114/19115 analog-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’s MCP19114 and MCP19115 family of Digitally Enhanced Power Analog controllers are the latest products to use Microchip’s highly flexible and highly configurable, DC/DC PWM controller technology,” said Bryan J. Liddiard, marketing vice president of Microchip’s Analog and Interface Products Division.

“Building on our MCP19110 and MCP19111 families, today’s devices continue to expand the capabilities of high-efficiency analog solutions, enabling new levels of flexibility and optimization, in a very small footprint."
