Microchip announces an expansion of 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 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 analogue-based controller, with the flexibility approaching that of a fully-digital power conversion solution. These new analogue 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-analogue control solutions offer the speed and responsiveness expected of a high-performance analogue control loop; the flexibility expected of a digital MCU; 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.
