The SGRB Series of space qualified DC-DC converters is specifically designed for the harsh radiation environment of space applications. Using advanced EPC Space GaN technology, the SGRB is radiation tolerant and achieves very high efficiency. A fixed-frequency reduced voltage switching topology results in very low input and output noise, making it suitable for use in telecommunication systems. VPT’s history of proven space flight heritage ensures long term performance and reliability.
Features:
Up to 400 W output power
High Efficiency up to 95% using GaN technology
Integrated EMI filter
141 V, 1 msec transient
80 V transient with reduced output power
Overvoltage protection
Current limit protection
Short circuit protection
4 bit word voltage adjustment
Power supply telemetry
Parallel up to 5 units with current share
Space-Level Characterizations:
TID performance to 100 krad(si) characterized for ELDRS
SEE performance to 85 MeV/mg/cm2. Transients are fully characterized for cross section and magnitude
