CIE Components in Electronics
Microchip has announced that it is expanding its Digitally Enhanced Power Analogue controller product line. With the introduction of the MCP19114 and MCP19115 devices, Microchip’s diverse range of intelligent DC/DC power-conversion solutions now includes 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 offers the power conversion performance typical of an analogue-based controller, but with the flexibility approaching that of a fully-digital power conversion solution. These new 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-analogue control solutions offer speed and responsiveness and the flexibility expected of a digital MCU; they operate across wide operating voltage ranges; support conventional 5, 12, and 24V rails; and meet automotive load-dump requirements. The MCP19114/19115 analogue-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.
The MCP19114 is available now for sampling and volume production in a 24-lead QFN 4 mm x 4 mm package. The MCP19115 is available now for sampling and volume production in a 24-lead QFN 5 mm x 5 mm package.
