Applications
The 5962-8670407VPA is purpose-built for space and high-reliability military power supply designs where radiation tolerance, wide input voltage range, and assured component traceability are mandatory. It controls DC-DC converters in satellite bus regulators, launch vehicle avionics, and defense electronics that must operate reliably across the -55°C to +125°C temperature range. Its 500 kHz switching frequency allows compact magnetic and capacitor sizing in weight-critical spacecraft power modules where every gram of payload mass has direct launch cost impact.

Frequently Asked Questions
Why is the 5962-8670407VPA's 50% maximum duty cycle important in push-pull or full-bridge converter topologies?
In push-pull and full-bridge converter topologies, limiting duty cycle to 50% prevents transformer core saturation by ensuring equal volt-second products on both halves of the AC excitation cycle. The 5962-8670407VPA enforces this limit internally, eliminating the need for external dead-time circuitry and reducing design complexity in satellite bus converters operating from 28 V spacecraft power buses within the 11 V to 30 V input range.
What UVLO thresholds does the 5962-8670407VPA use and how do they protect the power converter during spacecraft bus anomalies?
The 5962-8670407VPA employs a 16 V turn-on and 10 V turn-off UVLO (under-voltage lockout) threshold, creating a 6 V hysteresis window. During spacecraft bus droop events — such as battery discharge or eclipse transitions — the 6 V hysteresis prevents rapid oscillation between enabled and disabled states, protecting the downstream load from repeated inrush current stress and ensuring the converter only resumes regulation when the 28 V bus has fully recovered above 16 V.
How does the space-grade 5962 designation of the 5962-8670407VPA differ from a commercial-grade PWM controller for procurement purposes?
The 5962 Federal Stock Class designation certifies the device to MIL-PRF-38535 quality and screening requirements, including 100% electrical testing at -55°C and +125°C, radiation lot acceptance testing (RLAT), and full traceability documentation. This qualification adds significant unit cost over a commercial equivalent — typically 10x to 100x — but is mandated by NASA, ESA, and DoD procurement standards for Class B and Class S spacecraft components, making it non-substitutable with commercial PWM controllers in flight hardware.
