UCC2806DWTRG4

DC DC Switching Controllers Overview

The UCC2806DWTRG4 is a low-power, dual-output current-mode PWM controller manufactured by Texas Instruments. It operates within a supply voltage range of 15V and provides two independent output channels with a drive capability of 0.5A. The device supports multiple converter topologies including Boost, Flyback, Forward, Half-Bridge, Push-Pull, and Full-Bridge configurations. It features a switching frequency of 1 MHz and is housed in a 16-pin SOIC (DW) package. The component is designed for operation across an extended temperature range from -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Dual-output architecture enabling independent control of two power stages
• Current-mode PWM control strategy for improved transient response
• Supports versatile converter topologies including isolated and non-isolated designs

DC DC Switching Controllers Applications

• Multi-rail power supplies requiring synchronized or independent outputs
• Telecommunications equipment power systems
• Industrial control system power management

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the 'DW' package designation corresponds to the standard SOIC-16 footprint dimensions. Ensure the ordering part number matches the exact tape-and-reel quantity specifications provided in the official datasheet to avoid packaging discrepancies during assembly.

DC DC Switching Controllers Selection Notes

Select this component when dual-channel current-mode control is required for efficient power conversion. The 1 MHz switching frequency allows for reduced passive component size compared to lower-frequency alternatives. Consider the 0.5A output drive strength for gate driver requirements. Verify thermal performance within the specified -40°C to +85C operating range for the intended application environment.

DC DC Switching Controllers Part Context

This part belongs to the UCC28xx series of switching controllers from Texas Instruments. It is functionally related to the UC2846 family but offers enhanced dual-output capabilities and higher switching frequencies. The device serves as a core control element in DC-DC conversion circuits, replacing older single-channel solutions where multi-voltage rails are necessary.

DC DC Switching Controllers Replacement Considerations

The UC2806DWTR is the non-compliant equivalent. The UC2846DWTR offers similar functionality but lacks the dual-output configuration. Cross-reference pinouts and electrical parameters with official substitution guides before implementation.
