DC DC Switching Controllers datasheet and documents for UCC2893DG4
DC DC Switching Controllers Overview
The UCC2893DG4 is a current mode active clamp PWM controller manufactured by Texas Instruments, designed for 110-V applications. It integrates an N-channel clamp FET and features a 0.75V current sense threshold. The device supports flyback and forward converter topologies within the UCC289x family. It operates with a supply voltage range of 8.5 V to 14 V and delivers up to 1 A output current. The component is housed in a 16-pin SOIC package and is rated for operation between -40°C and +105°C.
DC DC Switching Controllers Feature Summary
- Integrates an N-channel clamp FET for simplified active clamp implementation
- Utilizes current mode control architecture for precise regulation
- Features a fixed 0.75V current sense threshold for consistent performance
DC DC Switching Controllers Applications
- Flyback converter designs
- Forward converter implementations
- Active clamp switching power supplies
DC DC Switching Controllers Procurement Notes
Verify the specific suffix 'DG4' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Ensure the 16-SOIC package variant matches the required PCB footprint. Cross-reference the 0.75V CS threshold requirement with system design specifications before finalizing procurement orders.
DC DC Switching Controllers Selection Notes
Select this component when designing isolated power supplies requiring active clamp reset techniques. The integrated N-channel FET reduces external component count compared to discrete solutions. Consider the 110-V input capability and current mode control benefits for efficiency optimization in flyback or forward topologies.
DC DC Switching Controllers Part Context
This part belongs to the UCC289x family of current mode active clamp PWM controllers from Texas Instruments. The family is engineered to simplify the implementation of various active clamp and reset switching power topologies. The DG4 suffix typically indicates a lead-free and RoHS-compliant version of the standard UCC2893 device.
DC DC Switching Controllers Replacement Considerations
The UCC2893D is the non-leaded equivalent without the G4 suffix. Verify pinout compatibility and electrical parameter alignment with the datasheet before substitution.
