DVPL0503S 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 and fast transient response. These converters are designed and manufactured in a facility qualified to ISO9001 and certified to MIL-PRF-38534 and MIL-STD-883.

DVPL0503S Series OUTPUT VOLTAGE TRIM The output voltage is set with an external resistor connected from the TRIM pin to GND pin. This resistor must have a tolerance of 1% or less to achieve an accurate output voltage. The default output voltage with the TRIM pin left floating is 0.8V. Figure 5 - Output Voltage Trim
