Voltage Mode Synchronous Buck PWM
DC-DC Converter with Integrated Inductor
External Output Voltage Programming
Description
Features
This Altera Enpirion solution is a Power System
on a chip (PowerSoC). It is specifically designed
to meet the precise voltage and fast transient
requirements of present and future high-
performance, low-power processor, DSP, FPGA,
ASIC, 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 as few as three external
components that include small value input and
output ceramic capacitors and a soft-start
capacitor.
The Altera Enpirion integrated inductor solution
significantly helps in low noise system design
and productivity by offering greatly simplified
board design, layout and manufacturing
requirements.
