Applications
The 5962-9457501VEA is designed for high-reliability DC-DC converter designs in military avionics, satellite power systems, and defense electronics where ceramic-package qualification and current-mode PWM control are mandatory. Its dual-output capability allows a single controller to manage two regulated rails, reducing BOM count in space-constrained power supply boards. The 8V to 14.5V input range suits 12V bus architectures common in rugged embedded computing platforms.

Frequently Asked Questions
What input voltage range does the 5962-9457501VEA support, and what bus architecture does that target?
The controller accepts an input voltage from 8V to 14.5V, with a nominal 12V operating point. This range is tailored for standard 12V intermediate bus architectures used in military and aerospace power distribution systems. Operating within this window ensures the internal oscillator and gate-drive circuits stay within their rated parameters across full temperature and supply tolerance.
How does current-mode control in the 5962-9457501VEA improve converter protection compared to voltage-mode control?
Current-mode control samples inductor current each switching cycle, providing cycle-by-cycle overcurrent protection that limits peak switch current to a safe level without requiring a separate current-sense comparator. This technique also improves load transient response by more than 2x compared to voltage-mode controllers, because the inner current loop acts as a first-order plant, simplifying outer voltage-loop compensation in designs with inductors from 10 µH to 100 µH.
Which high-reliability screening level applies to the 5962-9457501VEA, and what package does it use?
The part number prefix '5962' indicates compliance with MIL-PRF-38535 military screening. The device is housed in a 16-pin ceramic dual-in-line package (CDIP-16), which withstands operating temperatures from -55°C to +125°C and provides hermeticity required for long-term reliability in aerospace and defense applications where plastic packages are not permitted.
Can the 5962-9457501VEA drive two fully independent converter stages, and what are the output characteristics?
Yes, the controller provides two independent PWM output channels, each capable of driving external power MOSFETs or bipolar transistors. The duty cycle on each output can be programmed up to 50% per channel in push-pull topology or up to 100% in single-ended forward topologies, accommodating switching frequencies typically set between 20 kHz and 500 kHz by an external timing resistor and capacitor network.
