- enpirion® power solutions EN5311QI 1A Power So C Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION The Ultra-Low-Profile EN5311QI is targeted to applications where board area and profile are critical. EN5311QI is a plete power conversion solution requiring only two low cost ceramic MLCC caps. Inductor, MOSFETS, PWM, and pensation are integrated into a tiny 5mm x 4mm x 1.1mm QFN package. The EN5311QI is engineered to simplify design and to minimize layout constraints. 4 MHz switching frequency and internal type III pensation provides superior transient response. With a 1.1 mm profile, the EN5311QI is ideal for space and height constrained applications. A 3-pin VID output voltage selector provides seven pre-programmed output voltages along with an option for external resistor divider. Output voltage can be programmed on-the-fly to provide fast, dynamic voltage scaling.
