Microchip has expanded its Digitally Enhanced Power Analog controller product line with the introduction of the MCP19114 and MCP19115 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 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.
