Frequently Asked Questions
What switching frequency does the 5962-8990502VEA support and why does this benefit power supply size?
The 5962-8990502VEA operates at 1 MHz switching frequency, allowing use of smaller magnetic components and output capacitors in push-pull or bridge converter designs, reducing transformer size by approximately 10x compared to equivalent 100 kHz designs in space-grade power supplies.
What are the UVLO thresholds of the 5962-8990502VEA and how do they protect the power stage?
The 5962-8990502VEA has undervoltage lockout (UVLO) thresholds of 9.2 V (turn-on) and 8.4 V (turn-off), preventing the PWM controller from operating below the minimum input voltage of 12 V, protecting power MOSFETs and transformers from under-voltage stress during start-up and brown-out events.
Can the 5962-8990502VEA operate in current-mode control for tighter load regulation?
Yes, the 5962-8990502VEA can be configured in current-mode control in addition to voltage mode, allowing cycle-by-cycle current limiting and improved transient response in 30 V, 2 A switching power supplies, which is a critical feature for space and military power systems requiring tight output regulation.
What package does the 5962-8990502VEA use and why is it required for space-grade applications?
The 5962-8990502VEA uses a 16-pin ceramic DIP (R-GDIP-T16) package, which provides hermetic sealing and resistance to radiation and temperature extremes from -55°C to +125°C, meeting the mechanical and thermal requirements of space, satellite, and high-reliability military power converter designs.
