UCC3806DW

DC DC Switching Controllers Overview

The UCC3806DW is a low-power dual-output current-mode PWM controller manufactured by Texas Instruments. It supports Boost, Buck, Flyback, and Forward topologies with a switching frequency of 1 MHz and a maximum duty cycle of 50%. The device features a 5.1 V output voltage and 500 mA output current capability. It operates within a temperature range of 0°C to +70°C and is housed in a 16-pin SOIC package with SMD/SMT mounting style.

DC DC Switching Controllers Feature Summary

• Dual-output current-mode control architecture
• Supports multiple power converter topologies including Boost, Buck, Flyback, and Forward
• Integrated high-speed driver with fast fall time characteristics

DC DC Switching Controllers Applications

• Low power isolated DC-DC converters
• Flyback power supply designs
• Forward converter applications
• Boost and Buck regulator circuits

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and package variant when ordering, as the UCC3806 series includes different packaging options such as tube and reel configurations. Confirm moisture sensitivity levels and storage conditions prior to assembly. Ensure that the selected component matches the required operating temperature range for the intended application environment. Cross-reference datasheet specifications against system requirements to guarantee compatibility with existing design parameters.

DC DC Switching Controllers Selection Notes

Select the UCC3806DW for applications requiring dual outputs from a single controller with moderate power demands. Consider its 1 MHz switching frequency for compact magnetic component sizing. Evaluate thermal performance within the specified 0°C to +70°C range. Compare against similar controllers like the UC3846 if lower frequency or higher current drive is needed. Ensure the SOIC-16 footprint fits the PCB layout constraints.

DC DC Switching Controllers Part Context

The UCC3806 belongs to the UCC380x family of current-mode PWM controllers designed for low-power applications. It shares architectural similarities with other devices in the series but offers specific output current and frequency characteristics tailored for efficient small-form-factor power supplies. The DW suffix indicates a standard plastic SOIC package suitable for surface mount assembly processes.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitutes include the UCC3806PW (TSSOP-16 package) and UCC2806DWTR (extended temperature range -40°C to +85°C). Verify pinout compatibility and electrical parameter alignment before substitution.
