DV200-2800S Series
HIGH RELIABILITY DC-DC CONVERTERS
DESCRIPTION FEATURES
• High Reliability The DV200 series of high reliability, isolated DC-DC
converters is operable over a wide (-55 °C to +100 • Parallel Up to 5 Units With Current Sharing °C) temperature range with no power derating. • Output Voltage Trim Up +10% or Down –20% Unique to the DV200 series is a magnetic feedback • Wide Input Voltage Range: 16 to 50 Volts circuit that is radiation immune. Operating at a • Up to 200 Watts Output Power nominal fixed frequency of 500 kHz, these regulated, • Radiation Immune Magnetic Feedback Circuit isolated units utilize well-controlled undervoltage • NO Use of Optoisolators lockout circuitry to eliminate slow start-up problems. • Undervoltage Lockout The current sharing function allows a maximum of
