Key Features
- Dual output current-mode PWM control enables precise cycle-by-cycle current limiting for push-pull and half-bridge topologies
- Adjustable operation from 2.5V to 15V supply range provides design flexibility across multiple power stage configurations
- Low quiescent current consumption minimizes standby power loss in offline and telecom power supplies
Applications
The UCC3806J is well suited for push-pull, half-bridge, and full-bridge DC/DC converter designs in industrial and telecom power systems operating from 8V to 14.5V input. Its dual-output PWM drive and current-mode control simplify the design of isolated converters with tight load regulation. The ceramic DIP package ensures high reliability in harsh environments where moisture and mechanical stress are concerns.

Frequently Asked Questions
What input voltage range does the UCC3806J support and how does the adjustable mode extend design flexibility?
The UCC3806J operates from 8V to 14.5V input with a nominal 12V supply voltage. In adjustable mode it can operate from 2.5V to 15V, allowing the controller to be used in designs with lower voltage auxiliary rails. This flexibility makes it suitable for both 12V bus converters and lower-voltage point-of-load applications without changing the control IC.
Why is current-mode control in the UCC3806J advantageous for push-pull converter designs?
Current-mode control provides inherent cycle-by-cycle current limiting, protecting the power switches from saturation and overcurrent faults. In push-pull topologies it also helps balance the volt-second product across the transformer windings, reducing the risk of flux walking and core saturation. The UCC3806J's dual outputs directly drive both switches of a push-pull stage from a single 16-pin DIP package.
How does the UCC3806J's ceramic DIP package benefit reliability in industrial applications compared to plastic DIP?
The 16-pin ceramic dual-in-line package (CDIP) offers superior moisture resistance and hermetic sealing compared to plastic packages, which is critical in industrial environments with temperature cycling from 0°C to 70°C. Ceramic packages also have lower ionic contamination, reducing the risk of long-term parametric drift in high-reliability power supply designs for military-grade or industrial control equipment.
When would a designer choose UCC3806J instead of UCC2806 or UCC1806 variants for a converter design?
The UCC3806J is the commercial temperature grade version rated 0°C to 70°C, while UCC2806 covers the industrial range of -40°C to 85°C and UCC1806 supports -55°C to 125°C military range. For a cost-sensitive industrial SMPS in a controlled indoor environment, UCC3806J provides sufficient temperature coverage at a lower cost than the wider-range variants, while all three share identical electrical parameters and dual PWM output drive characteristics.
