SVRPL3R306SG Point of Load DC-DC Converter

The SVRPL Series of space qualified point-of-load DC-DC converters is specifically designed for the harsh radiation environment of space applications and is designed in accordance with the Aerospace TOR requirements. Performance is guaranteed through the use of hardened semiconductor components and analysis. The SVRPL Series has been characterized for Total Ionizing Dose (TID) performance including Enhanced Low Dose Rate Sensitivity (ELDRS) and for Single Event Effects (SEE) per VPT’s DLA-approved Radiation Hardness Assurance (RHA) plan per MIL-PRF-38534, Appendix G, Level R.

The SVRPL3R306SG is based on the Intersil ISL70001ASEH radiation-hardened monolithic buck regulator. It is designed to operate from a nominal 3.3 V or 5 V bus. The SVRPL3R306SG supplies low voltages at 6 A with high efficiency and fast transient response, making it an ideal choice to supply point-of-load applications such as high-performance space processors.

Combine our extensive family of DC-DC converters for space with these point of load converters for space to create a light weight, extremely efficient, space-ready power system.
