EN5337QI Datasheet | Altera

Enpirion® Power Datasheet EN5337QI 3A Power So C Voltage Mode Synchronous Buck PWM DC-DC Converter with Integrated Inductor FDescription The EN5337QI is a Power Supply on a Chip (Power So C) DC-DC converter. It integrates MOSFET switches, all small-signal circuits, pensation, and the inductor in an advanced 4mm x 7mm QFN package. The EN5337QI 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 distributed power architectures. Advanced circuit techniques, ultra high switching frequency, and very advanced, high-density, integrated circuit and proprietary inductor technology deliver highquality, ultra pact, non-isolated DC-DC conversion. The Altera Enpirion solution 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 plete power solution helps to enable an overall system cost savings. All Altera Enpirion products are Ro HS pliant and lead-free manufacturing environment patible.
