Altera Enpirion EN5337QI 3A Buck Converter with Integrated Inductor

Named to EDN "Hot 100 Products" 2009, Power Category

Altera Enpirion EN5337QI 3A voltage mode synchronous buck converter with integrated inductor is a power supply on a chip (PwrSoC) DC-DC converter. The EN5337QI delivers high-quality, ultra-compact, non-isolated DC-DC conversion through advanced circuit techniques and ultra high switching frequency. The Enpirion EN5337QI integrates MOSFET switches, all small-signal circuits, compensation, and the inductor in an advanced 4mm x 7mm QFN package. This Enpirion 3A buck converter features 92% peak efficiency and 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 distributed power architectures.
