Product Overview
The Ultra-Low-Profile EN5312QI is targeted to applications where board area and profile are critical. EN5312QI is a complete power conversion solution requiring only two low cost ceramic MLCC caps. Inductor, MOSFETS, PWM, and compensation are integrated into a tiny 5mm x 4mm x 1.1mm QFN package. The EN5312QI is engineered to simplify design and to minimize layout constraints. 4 MHz switching frequency and internal type III compensation provides superior transient response. With a 1.1 mm profile, the EN5312QI is ideal for space and height constrained applications.
