vpr Power Your Critical Mission Today Models Available Input: 3.1 V to 13.2 V 9 A output Qualified to MIL-PRF-38534 Class H and Class K 1.0 DESCRIPTION The SVPL Series of space qualified point-of-load DC-DC converters is specifically designed for the harsh radiation environment of space applications. Performance is guaranteed through the use of hardened semiconductor components and analysis. The SVPL 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 SVPL1209SG is based on the Intersil ISL70003ASEH radiation-hardened monolithic buck regulator. It is designed to operate from nominal bus voltages from 3.3 V to 12 V. The SVPL1209SG supplies low voltages at 9 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. 1.1 FEATURES • Operates from 3.1 - 13.2 V input • Adjustable Output from 0.8 - 5 V • Up to 9 Amps Output • High Efficiency, up to 93% • High Power Density, up to 132 W/in3 • Output Enable Control • Low Output Noise • Over Current Protection • Synchronizable to an external clock 1.2 SPACE LEVEL CHARACTERIZATIONS • Total Ionizing Dose Performance • High Dose Rate [50-300 rad(Si)/s] > 100 krad(Si) • Low Dose Rate [<10 mrad(Si)/s] > 100 krad(Si) • Single Event Effects Performance • SEL, SEB, and SEGR LETth> 85 MeV-cm2/mg • SEFI Threshold LETth > 42 MeV-cm2/mg • SEFI X-section (LETeff = 85 MeV-cm2/mg) < 1.18x10-7 cm2 • SET fully characterized for cross section and magnitude • Operation from -55 °C to +125 °C • Worst-case analysis, stress, radiation, reliability reports available 1.3 MANUFACTURING AND COMPLIANCE • Qualified to MIL-PRF-38534 Class H and Class K, DLA SMD # 5962-17232 • MIL-PRF-38534 element evaluated components • Manufactured in a MIL-PRF-38534 Class H and Class K facility • MIL-STD-883 • ISO-9001 1.4 PACKAGING • Low-profile: 1.110” x 1.110” x 0.276” • Max weight: 22 g • Precision seam-welded hermetic metal case • Standard gullwing or optional straight-lead versions available 1.5 SIMILAR PRODUCTS AND ACCESSORIES • SVPL3R306SG 6 A space qualified point of load DC-DC converter • SVPL3R312SG 12 A space qualified point of load DC-DC converter • SVGA0510SG 10 A space qualified point of load DC-DC converter • SVGA0515SG 15 A space qualified point of load DC-DC converter • Custom versions available • Space qualified isolated DC-DC converters. 6 - 100 W Products and reports described in this datasheet are subject to all export license restrictions and regulations which may include but are not limited to ITAR (International Traffic in Arms Regulations) and the Export Administration and Foreign Assets Control Regulations.

vpr Power Your Critical Mission Today O- 1. Rtrim should be connected directly across pins 11 and 12 as close as possible to the SVPL. 2. AGND should be connected to gNd close to the SVPL. Voltage difference between the AGND and the GND pins greater than 0.3 V may result in regulation error and/or damage to the SVPL. 3. If not using EN and VIN < 5.15 V, pin 7 can be connected directly to VIN. For VIN > 5.15 V, pin 7 can be pulled up toward VIN through a 49.9 kO - 100 kO resistor. 4. If not synchronizing converters, connect pin 9 to GND. 5. If not using PGOOD, leave pin 10 open. 6. Rcomp and Ccomp...
