Power analog controllers target DC/DC power-conversion applications
The expansion helps to grow Microchip’s diverse range of intelligent DC/DC power-conversion solutions to include controllers supporting flyback, boost and SEPIC topologies.
The additional 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. The 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 42 V, and have integrated MOSFET drivers configured for step-up applications.
The MCP19114 Flyback Stand-Alone Evaluation Board is intended to demonstrate how the MCP19114 device operates in a synchronous flyback topology. the board is configured to regulate load current and is also well-suited to drive LED loads.
The MCP19114 is priced at $49.99) and is available now offered with a flyback design supporting 0 V to 50 V output from an 8 V to 14 V 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, PICkit Serial Analyzer, and the MPLAB XC8 Compiler.
Availability and Pricing
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.
