Description

IRMCS3043 is a reference design platform for IRMCF343, a high performance RAM-based motion control IC designed

primarily for appliance applications, up to 1.7kW continuous input power. It’s mainly aimed to achieve simple, low cost and

high performance solutions for advanced appliance motor control. It consists of an active PFC frond-end and an inverter

stage, both of which are controlled by the IRMCF343 digital IC

(IRGP4063DPbF) for the PFC and an integrated power module (IRAMX16UP60A-2) for the inverter, which are part of

iMOTION

spending development effort usually required in the traditional DSP or microcontroller based system. The complete B/Ms,

schematics and layout are provided so that the user can adapt and tailor the design per application needs.
