DVPL0505S Series
HIGH 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 MILPRF-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

The output voltage will follow this pin. Used for output voltage sequencing or tracking. If not used, the Track pin should be connected to Vin. Positive Input Voltage Connection Case Connection Positive Output Voltage Connection Common Return Connection Trim pin sets output voltage with a resistor to Common Logic Low = Disabled Output. Connecting the inhibit pin to common causes converter shutdown. Logic High (open collector or open drain) = Enabled Output. Leave open if not used.
