Overview
The UCC28051DG4 is a power factor correction controller from Texas Instruments, designed for discontinuous (transition) mode operation. It operates at a switching frequency of 200kHz and is housed in an 8-SOIC package with a width of 3.90mm. The device supports a supply voltage range of 12V to 18V and features a startup current of 75 µA. It is rated for an operating temperature range of -40°C to 105°C.
Feature Summary
- Supports discontinuous transition mode power factor correction control
- Integrated soft-start and cycle-by-cycle current limiting
- High precision oscillator for stable frequency operation
Applications
- Universal AC input power supplies
- Power factor correction stages in adapters
- Industrial power management systems
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free packaging compliance as per manufacturer standards. Confirm the SOIC-8 package dimensions match the design footprint requirements. Ensure the operating temperature range aligns with the thermal constraints of the target application environment before finalizing procurement.
Selection Notes
Select this component for applications requiring transition mode PFC control with a 200kHz switching frequency. The 8-SOIC package offers surface mount convenience. Consider the 12V to 18V supply range when designing the auxiliary power circuitry. Verify compatibility with the intended load conditions and thermal dissipation capabilities within the system architecture.
Part Context
The UCC28051DG4 belongs to the UCC2805x series of power factor correction controllers. This series is engineered for high-efficiency AC-DC conversion. The device integrates essential protection features to ensure reliable performance in various power supply designs, serving as a key component for meeting regulatory efficiency standards.
Replacement Considerations
The UCC28051D is the non-RoHS equivalent part number within the same product family. Both devices share identical electrical specifications and pinouts, differing primarily in manufacturing compliance details.
