DataSheeT enpirion power solutions EN5336QI 3A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES The EN5336QI is an Intel Enpirion Power System on Integrated INDUCTOR, MOSFETS, Controller a Chip (PowerSoC) DC-DC converter. It is specifically Footprint 1/3rd that of competing solutions designed to meet the precise voltage and fast Low Part Count: only 3 MLC Capacitors transient requirements of present and future high- Up to 10W continuous output power performance, low-power processor, DSP, FPGA, memory boards and system level applications in a 5MHz operating frequency distributed power architecture. Advanced circuit High efficiency, up to 93% techniques, ultra high switching frequency, and very VOUT accuracy 3% over line, load and temp advanced, high-density, integrated circuit and Wide input voltage range of 2.375V to 6.6V proprietary inductor technology deliver high-quality, 3-pin VID output voltage select to choose one of ultra compact, non-isolated DC-DC conversion. 7 pre-programmed voltage levels Intel Enpirion solution significantly helps in system Output enable pin and Power OK signal design and productivity by offering greatly simplified Programmable soft-start time board design, layout and manufacturing requirements. In addition, a reduction in the number Programmable over-current protection of vendors required for the complete power solution Thermal shutdown, short circuit, and UVLO helps to enable an overall system cost savings. Output over-voltage protection Intel Enpirion products are RoHS compliant and lead- RoHS compliant, MSL level 3, 260C reflow free manufacturing environment compatible.
