Power Matters

System view of space products

Power Matters

System engineers always look at a satellite as a system

Interfaces and partitioning are done at this level of engineering

Without coordination of component development • Difficult and limited choices in partitions • Performance, power, weight, and cost are sacrificed • Interoperability assurance diminished

System View Device Development


Power Matters

If the device designers look at the system design to define products • Digital interface formats aligned • Digital and analog physical interfaces aligned • Power generation optimized for load and rails • No more “level converters”, “signal dividers”, extra clock channels, … • Product introductions aligned • Reliability architected into the component systems



Power Matters

To take advantage of this advanced view of product definition

• Companies can align products in their portfolio • Companies can partner • General standards



Size, power, cost, performance optimization

Power Matters

Examples • High speed digital interfaces, standard, and custom • Analog converters (A/D, D/A) dynamic range alignment • Integrated voltage and current references • POL devices and FPGA or ASIC current and voltage load matching • Consistent cross device radiation performance (weakest link) • High temperature switching device drivers optimized to switching device

characteristics • Serial communication width appropriate for the device technologies involved • FPGA’s control and monitoring clock and power generation. • Optimized device power down.

Efficient Solar Panel Conversion

16 © 2012 Microsemi Corporation

MSCC is enhancing system efficiency by direct conversion from the Solar Panel • Typically 100 v to 120 v • Instead of 100 v to 28 v @ 75% and then from 28 v to 3.3 v @ 75% efficiency, the SA50-120 converts from 120 v to

3.3 v @ 86%.

Soon to be released SB30-100 family will provide lower power system requirements SA50 and SB30 families interface directly with switching and linear MSCC POLs to

provide total system power requirements
