Key Features
- Current-mode PWM control with 8 V to 40 V input range covers a wide set of DC-DC conversion topologies including full-bridge and push-pull
- Military-grade 16-pin ceramic DIP (R-GDIP-T16) package provides high reliability under harsh thermal and vibration environments
- Multi-topology support — buck, boost, flyback, forward, full-bridge, half-bridge, and push-pull — reduces SKU proliferation in defense power systems
Applications
5962-8680603VEA is designed for mission-critical power conversion in military avionics, satellite payloads, and space-grade electronics where ceramic packaging and radiation tolerance are mandatory. It also serves industrial high-reliability applications such as downhole drilling tool power supplies and military ground vehicle DC-DC converters operating from 8 V to 40 V input rails. The multi-topology flexibility allows a single controller design to support several output configurations across a defense product line.

Frequently Asked Questions
What switching topologies does 5962-8680603VEA support and what input voltage range is required?
5962-8680603VEA supports buck, boost, flyback, forward, full-bridge, half-bridge, and push-pull topologies with an input voltage range of 8 V to 40 V, nominally designed for 15 V rails. Current-mode PWM control provides inherent cycle-by-cycle current limiting across all supported topologies, making it a versatile choice for military multi-output power supplies.
Why is the ceramic DIP package of 5962-8680603VEA preferred in aerospace and defense designs over plastic packages?
The R-GDIP-T16 ceramic 16-pin DIP package offers significantly higher moisture resistance, a thermal coefficient closer to ceramic substrate PCBs, and withstands operating temperatures beyond commercial ranges, making it mandatory for MIL-STD and NASA programs. Plastic QFP or SOIC alternatives typically fail hermetic seal requirements demanded by DSCC drawing 5962-86806, which this device satisfies. The ceramic body also provides improved radiation tolerance for low-earth-orbit satellite payloads operating under 40 V bus.
When is 5962-8680603VEA a suitable lower-risk replacement compared with commercial-grade UC3845 PWM controllers?
5962-8680603VEA is preferred over commercial UC3845 variants when the end-product must pass MIL-PRF-38535 Class V screening, operate reliably across junction temperatures exceeding 125°C, or survive 40 V transients on a 28 V mil-aero bus. Commercial UC3845 is rated to 30 V maximum input, while this device extends to 40 V, providing an extra 10 V headroom that prevents crowbar trips during load dump events in vehicle power systems.
How many output channels can a single 5962-8680603VEA drive in a full-bridge topology?
In a full-bridge configuration, one 5962-8680603VEA drives 4 external switching transistors through complementary PWM outputs, delivering a single isolated DC output at duty cycles up to approximately 50% per switch pair. The 16-pin CDIP package provides dedicated timing, current-sense, and compensation pins that keep the full-bridge control loop stable across the 8 V to 40 V input range without additional gate-drive ICs in lower-current designs.
