Frequently Asked Questions
What input voltage range does the 5962-8670401VPA support, and how does the UVLO protect the converter?
The 5962-8670401VPA accepts an 11 V to 28 V input range. The dual under-voltage lockout thresholds start the controller at 16 V and shut it down at 10 V, preventing operation at insufficient supply levels and protecting downstream circuitry from under-voltage damage during power-up and brown-out events.
For a satellite power-bus design, why is 100% duty-cycle capability important in the 5962-8670401VPA?
In satellite applications, input voltage can droop significantly during eclipse or battery-discharge phases. The 5962-8670401VPA's 100% duty-cycle capability allows the switch to remain on continuously, maximising energy transfer when input voltage approaches output voltage and ensuring uninterrupted regulation during worst-case low-input conditions at up to 1 A output.
How does the 5962-8670401VPA's 500-kHz switching frequency affect magnetics selection in aerospace designs?
Operating at 500 kHz allows the use of smaller inductors and capacitors compared to lower-frequency controllers, reducing board weight and volume — critical constraints in aerospace and satellite designs. The current-mode PWM control also simplifies compensation and improves loop stability across the 11 V to 28 V input range at 1 A maximum load.
When would a designer choose the 5962-8670401VPA over a commercial-grade PWM controller?
The 5962-8670401VPA is a space-grade, MIL-spec part (5962 designator) suited for programs requiring radiation tolerance, screening to MIL-PRF-38535, and extended temperature operation. Commercial-grade parts lack these qualifications, making this device the necessary choice for Class B or Class S space missions, avionics, and military power supplies where field-serviceability is impossible.
