Digitally-Enhanced Power Analog Controllers with Integrated MCU
Microchip Technology Inc. today announced an expansion of its digitally-enhanced power analog controller product line. With the introduction of the MCP19114 and MCP19115 devices, Microchip's diverse range of intelligent dc-dc power-conversion solutions grows to include controllers supporting flyback, boost and SEPIC topologies. 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."
Microchip’s MCP19114 Flyback Standalone Evaluation Board (part # ADM00578, $49.99), also announced today, is available now. This evaluation board is offered with a flyback design supporting 0V to 50V output from an 8V to 14V input. Microchip’s full suite of development tools support the MCP19114 and MCP19115 power controllers, including the MPLAB® X Integrated Development Environment (IDE), PICkit™ 3 (part # PG164130, $44.95), PICkit Serial Analyzer (part #DV164122, $49.99), and the MPLAB XC8 Compiler.
The MCP19114 is available now for sampling and volume production in 24-lead QFN 4 mm x 4 mm packages, for $2.61 each, in 10,000-unit quantities. The MCP19115 is available now for sampling and volume production in 24-lead QFN 5 mm x 5 mm packages, for $2.78 each, in 10,000-unit quantities.
