Z Series
The Z series are low output voltage, high current DC-DC converters for digital signal processors, FPGA, ASIC, and other digital applications. Additionally, with its excellent efficiency performance, the platform is well suited as the primary down converter of a DPA system. The Z series offers three output current platforms, 25A (ZA), 50A (ZB) and 125A (ZC). Similar functional features can easily be included as needed for specific design requirements. Each of these platforms can be designed to operate with any of popular satellite power bus voltages from 20V to 100V.

Applications: DSP, ASIC, FPGA and as down converter in distributed power Architecture, 18 years life in orbit

Key Features:

• Low output voltage: 1 to 5VDC
• 3 output current platforms, 25A (ZA)/50A (ZB)/125A (ZC)
• 4 input ranges 18V – 110V DC
• Main output user adjustable ±10%, during flight or tuning on ground
• Integrated EMI filter, provides EMC compliance to various satellite platforms
• Use of I3M magnetic (patent) and use of hy-bridge rectification with synchronous rectifiers (patent), ensures ultra high efficiency
• Single point failure free with respect output over-voltage
• Efficiency >90% EOL
