DVPL0505S SeriesHIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION The DVPL series of high reliability DC-DC converters is operable over the full military (-55 °C to +125 °C) temperature range with no power derating. Operating at a nominal fixed frequency of 300 kHz, these regulated, non-isolated converters are optimized for low voltage point of load applications with high efficiency synchronous rectification, fast transient response, and power sequencing capability. These converters are designed and manufactured in a facility qualified to ISO9001 and certified to MIL-PRF-38534 and MIL-STD-883. This product may incorporate one or more of the following U.S. patents: 5,784,266 5,790,389 5,963,438 5,999,433 6,005,780 6,084,792 6,118,673 FEATURES • High Reliability • Operates From 5V or 3.3V Input • Adjustable Output Voltage, 0.8V to 3.4V • Up to 5 Amps or 16W Output • High Efficiency, Up to 97% • Output Voltage Sequencing • Output Voltage Tracking • Operation Into a Pre-Biased Output • Output Inhibit Control • Low Output Noise • NO Use of Optoisolators • Over Current and Short Circuit Protection • Precision Projection Welded Hermetic Package • Meets MIL-STD-461C and MIL-STD-461D EMC Requirements When Used With VPT DC-DC Converters and EMI filters • Additional Environmental Screening Available • MIL-PRF-38534 Element Evaluated Sales Information: Phone: (425) 353-3010 Fax: (425) 353-4030 E-mail: [email protected]
