ICE1PCS01G PFC Controller - Equivalent & Substitute Parts

Part Overview

The ICE1PCS01G is a Power Factor Correction (PFC) controller IC manufactured by Infineon Technologies, designed for continuous conduction mode (CCM) operation at 133kHz switching frequency. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production support. The part operates within a 10.2V to 21V supply voltage range and is housed in an 8-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICE1PCS01G is based on the following critical parameters that must be maintained or exceeded:

• Operating Mode: Continuous Conduction (CCM) capability is mandatory for functional equivalence
• Package Compatibility: 8-SOIC surface mount package with identical pin pitch (0.154", 3.90mm width) ensures PCB-level compatibility
• Supply Voltage Range: The substitute must accommodate the 10.2V ~ 21V operating window
• Operating Temperature Range: -40°C ~ 125°C operational envelope must be supported
• Switching Frequency Capability: The substitute must support operation at or near 133kHz, or provide programmable/adjustable frequency within acceptable design margins

The UCC28180D from Texas Instruments meets these substitution criteria through its CCM mode support, identical 8-SOIC package, compatible voltage range, matching temperature specifications, and adjustable switching frequency range (18kHz ~ 250kHz) that encompasses the 133kHz requirement.

Engineering Selection Recommendations

The UCC28180D is the manufacturer-recommended substitute for the obsolete ICE1PCS01G. Selection of this alternative is justified by the following factors:

• Product Status: The ICE1PCS01G is obsolete, making the active UCC28180D the appropriate choice for continued production and new designs
• Regulatory Compliance: The UCC28180D carries ROHS3 compliance certification, meeting current environmental and regulatory requirements
• Packaging Equivalence: Identical 8-SOIC package ensures direct PCB compatibility without layout modifications
• Functional Compatibility: Both devices operate in CCM mode with matching temperature specifications and compatible voltage ranges
• Improved Specifications: The UCC28180D offers superior moisture sensitivity (MSL 1 vs. MSL 3) and lower startup current (75 µA vs. 100 µA)

Frequently Asked Questions (FAQ)

Q: Can the UCC28180D be used as a direct replacement for the ICE1PCS01G without PCB modifications?

A: Yes. Both devices use the 8-SOIC package with identical pin pitch and width specifications, enabling direct PCB compatibility. No layout changes are required.

Q: What is the key difference in switching frequency between these parts?

A: The ICE1PCS01G operates at a fixed 133kHz, while the UCC28180D provides an adjustable frequency range of 18kHz to 250kHz. The design must configure the UCC28180D to operate at 133kHz through appropriate external component selection.

Q: Are there any voltage supply differences I should consider?

A: The ICE1PCS01G supports 10.2V ~ 21V, while the UCC28180D is specified at 21V. Designs operating below 10.2V may require additional evaluation. For applications within the 10.2V ~ 21V window, the UCC28180D is suitable.

Q: What are the moisture sensitivity implications?

A: The ICE1PCS01G has MSL 3 (168-hour limit), while the UCC28180D has MSL 1 (unlimited). The UCC28180D offers superior moisture tolerance, reducing handling and storage constraints.

Q: Is the UCC28180D RoHS compliant?

A: Yes, the UCC28180D is ROHS3 compliant. The ICE1PCS01G RoHS status is not specified in the available data.
