Overview
The UC2852DTR is a high power-factor preregulator integrated circuit manufactured by Texas Instruments. It operates in continuous conduction mode (CCM) with a fixed switching frequency of 200 kHz. The device is housed in an 8-pin SOIC package and supports surface-mount installation. It functions within a temperature range of -40°C to +85°C and draws a startup current of 400 µA. This component is classified under Power Factor Correction (PFC) products within the PMIC category.
Feature Summary
- Designed for high power-factor preregulation applications
- Supports continuous conduction mode operation
- Integrated fixed switching frequency control
Applications
- High power-factor preregulators
- Power factor correction circuits
- Switching power supply inputs
Procurement Notes
Verify that the UC2852DTR is suitable for your design, noting it may not be recommended for new designs per manufacturer guidance. Confirm the SOIC-8 package compatibility and ensure the 200 kHz switching frequency aligns with system requirements. Check for alternative components if availability is constrained due to lifecycle status.
Selection Notes
Select this part for applications requiring CCM PFC control at 200 kHz. Ensure the PCB layout supports SOIC-8 surface mounting. Verify thermal management capabilities for the specified operating temperature range. Consider the 400 µA startup current impact on pre-regulation stages during initial power-up phases.
Part Context
The UC2852 series includes variants like UC2852N and UC2852DTR. While the UC2852N uses a PDIP-8 through-hole package, the DTR variant utilizes an SOIC-8 surface-mount format. Both share similar functional characteristics as high power-factor preregulators, differing primarily in packaging and mounting style preferences for manufacturing processes.
Replacement Considerations
Check for updated Texas Instruments recommendations as the UC2852DTR may not be recommended for new designs. Evaluate equivalent PFC controllers from the same family or newer generations that offer improved availability or performance metrics while maintaining compatible interface specifications.
