UCC2806DW

DC DC Switching Controllers Overview

The UCC2806DW is a low-power, dual-output current-mode PWM controller manufactured by Texas Instruments. It supports Boost, Flyback, and Forward topologies with a switching frequency of 1 MHz and a maximum duty cycle of 50%. The device provides a regulated output voltage of 5.1 V and can source up to 500 mA of output current. It operates within a temperature range of -40°C to +85°C and is housed in a SOIC-16 surface-mount package.

DC DC Switching Controllers Feature Summary

• Dual-output architecture designed for applications requiring two independent power rails from a single controller.
• Current-mode control technique ensures stable operation across varying load conditions and input voltages.
• Integrated regulation circuitry delivers a fixed 5.1 V reference output for auxiliary power supply needs.

DC DC Switching Controllers Applications

• Power supplies utilizing Flyback topology
• Systems employing Boost converter configurations
• Forward converter based power architectures

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-16 tube packaging when ordering. Confirm that the required operating temperature range of -40°C to +85°C aligns with your system's thermal design requirements. Ensure the 1 MHz switching frequency is compatible with your magnetic component selection and electromagnetic interference constraints.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring dual outputs with integrated regulation. Consider the 500 mA drive capability for controlling external MOSFETs or driving transformer windings directly. Evaluate the SOIC-16 footprint against available board space. Compare against UC2846 if higher switching frequencies or different pinouts are necessary for the specific application.

DC DC Switching Controllers Part Context

This part belongs to the UCC2806 series of low-power controllers. It shares functional similarities with the UC2846 but offers optimized characteristics for lower power applications. The device integrates essential PWM logic and driver stages into a compact package, reducing external component count compared to discrete solutions.

DC DC Switching Controllers Replacement Considerations

The UC2846DW is a documented alternative within the same family offering similar current-mode control features. Verify pin compatibility and electrical parameter alignment before substitution. Other variants like UCC2806MTR provide equivalent functionality in SSOP-16 packaging.
