ORLANDO, FL — (Marketwire) — 02/06/12 — Vicor Corporation (NASDAQ: VICR), today announced the introduction of the for DC-DC converters. Supporting 48V DC-DC converter designs up to 14A for data communications and telecommunication applications, the QuietPower QPI-21 provides > 99.5% efficiency while achieving a new level of filtering performance.
The QuietPower QPI-21 is packaged in a high density, one-square-inch Land Grid Array (LGA) surface mount package that reduces PCB board area consumed by EMI filtering, ensuring ultra efficient board utilization. The filter-s 0.2″ height maximizes airflow for space constrained designs, making it an ideal fit for advanced blade-architecture applications. These density advantages are complemented by new performance enhancements enabling higher frequency attenuation across various system configurations than earlier-generation QuietPower QPI-series filters.
The QuietPower QPI-21 attenuates conducted common mode (CM) and differential mode (DM) noise over the CISPR22 frequency range of 150 kHz to 30 MHz (45dB for CM and 80dB for DM attenuation at 250 KHz). The filter is designed for use in 48V bus (36 – 76V) systems, with 100VDC/100ms surge capability, and operates over a wide temperature range of -40°C to +125°C and up to an ambient temperature of 65°C without de-rating. The QPI-21 supports the PICMG® 3.0 specification for filtering system boards to the EN55022 Class B limits and is also tolerant to all DC-DC converter grounding schemes.
The QuietPower QPI-21 is the newest addition to the Picor QuietPower portfolio of high density EMI input and output filters, addressing multiple voltage rail/bus needs for applications in aerospace and industrial, in addition to datacom and telecom. The QuietPower QPI-21, like all QuietPower filters, is a universal filter for use with DC-DC converters from any manufacturer.
“The combination of form factor, attenuation performance, and efficiency within the QuietPower QPI-21 exceeds the capabilities of conventional passive filters,” said Chester Firek, Senior Product Marketing Manager, Picor. “These advantages distinguish the QuietPower QPI-21 as the ideal EMI filter for demanding, high density datacom and telecomm systems with board space and/or airflow constraints.”
Pricing and Availability
The QuietPower QPI-21 is available in two package types: the QPI-21LZ (lidded LGA package) and the QPI-21LZ-01 (open frame LGA package). Both QPI-21 package types are available at $17.04 for OEM quantities. For a datasheet and more information on QuietPower QPI-21, visit . To order, email or call 1-800-735-6200.
