Product Overview The Ultra-Low-Profile EN5312Q is targeted to applications where board area and profile are critical. EN5312Q is a complete power conversion solution requiring only two low cost ceramic MLCC caps. Inductor, MOSFETS, PWM, and compensation are integrated into a tiny 4mm x 5mm x 1.1mm QFN package. Engineered to minimize all sources of converter noise, the EN5312Q eases design and layout constraints. 5 MHz switching frequency and internal type III compensation provides superior transient response. With a 1.1 mm profile, the entire layout can occupy as little as 28mm2 of board area.
