Description
The EN5336QI is a Power System on Silicon DCDC converter. It is specifically designed to meet the precise voltage and fast transient requirements of present and future high-performance, low-power processor, DSP, FPGA, memory boards and system level applications in a distributed power architecture. Advanced circuit techniques, ultra high switching frequency, and very advanced, high-density, integrated circuit and proprietary inductor technology deliver high-quality, ultra compact, non-isolated DC-DC conversion. Operating this converter requires only small value input and output ceramic capacitors, a soft-start capacitor and a resistor divider for voltage feedback to set the output voltage to the desired value.
