Microchip Technology introduced their MCP19111 Digitally Enhanced Power Analog controller. The MCP19111 is a new hybrid, digital and analog power-management device. The controller increases the capabilities of high-efficiency, analog-based power designs. The MCP19111 controller is priced at $2.81 each. It is available in a 5×5 mm, 28-pin QFN package.
The MCP19111 Digitally Enhanced Power Analog family operates across a wide voltage range of 4.5 to 32V and offers a significant increase in flexibility over conventional analog-based solutions. According to Microchip, the device is the world’s first hybrid, mixed-signal power-management controller. It integrates an analog-based PWM controller with a fully functional Flash-based microcontroller. This integration offers the flexibility of a digital solution, with the speed, performance and resolution of an analog-based controller.
The Microchip MCP19111 devices support operation up to 32V, and have integrated MOSFET drivers configured for synchronous, step-down applications. The broad operating range and integrated, mid-voltage synchronous drivers support high-efficiency, power-dense conversion with fast, analog-based control.
