EN5330
3A Voltage Mode Synchronous Buck PWM DC-DC Converter with Integrated Inductor

July 2007

The EN5330 is a Power System on a Chip DCDC converter. It is specifically designed to meet the precise voltage and fast transient requirements of present and future highperformance, 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 highquality, ultra compact, non-isolated DC-DC conversion. Operating this converter requires only three external components that include small value input and output ceramic capacitors and a soft-start capacitor.

The EN5330 significantly helps in system design and productivity by offering greatly simplified board design, layout and manufacturing requirements. In addition, a reduction in the number of vendors required for the complete power solution helps to enable an overall system cost savings.
