IR1152SPBF PFC Controller - Equivalent & Substitute Parts

Part Overview

The IR1152SPBF is a Power Factor Correction (PFC) controller IC operating in Continuous Conduction Mode (CCM) at 66kHz switching frequency, housed in an 8-SOIC surface mount package. This device is classified as obsolete, making identification of functionally compatible alternatives essential for ongoing system support and new design implementations. The IR1152SPBF was designed for applications requiring active power factor correction with fixed-frequency operation and low startup current characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR1152SPBF is determined by the following critical parameters:

Functional Compatibility Criteria:

• Operating mode: Continuous Conduction (CCM)
• Package type: 8-SOIC surface mount form factor
• Switching frequency capability: Must support or encompass the 66kHz operating point
• Supply voltage compatibility: Must accommodate the 14V ~ 17V input range

Electrical Compatibility Criteria:

• Startup current characteristics
• Operating temperature range coverage
• Supply voltage specifications

The UCC28180D from Texas Instruments satisfies these substitution criteria through identical package geometry, CCM mode operation, and switching frequency range that includes the 66kHz specification point. Both devices are designed for PFC controller applications with 8-SOIC packaging, enabling direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The UCC28180D is the manufacturer-recommended substitute for the IR1152SPBF. Selection of this alternative is justified by the following factors:

Product Status Consideration: The IR1152SPBF is classified as obsolete, creating supply chain risk and limiting long-term availability. The UCC28180D maintains active product status with established supply channels.

Compliance and Certification: The UCC28180D carries ROHS3 compliance certification and superior moisture sensitivity rating (MSL 1 vs. MSL 2), providing enhanced reliability for storage and handling. Both devices maintain REACH Unaffected status and EAR99 ECCN classification.

Functional Equivalence: Both devices operate in CCM mode within identical 8-SOIC packages, supporting direct board-level substitution without layout modifications. The UCC28180D's programmable frequency range (18kHz ~ 250kHz) encompasses the IR1152SPBF's fixed 66kHz operation point.

Operating Parameter Differences: The UCC28180D specifies 21V supply voltage versus the IR1152SPBF's 14V ~ 17V range, and exhibits higher startup current (75 µA vs. 26 µA). System design must accommodate these electrical differences through appropriate power supply configuration and bias circuit adjustment.

Frequently Asked Questions (FAQ)

Q: Can the UCC28180D directly replace the IR1152SPBF without circuit modifications?

A: Both devices share identical 8-SOIC package geometry and CCM operating mode, enabling physical substitution. However, the UCC28180D's different supply voltage specification (21V vs. 14V ~ 17V) and startup current (75 µA vs. 26 µA) require evaluation of the bias supply circuit and startup behavior to ensure system compatibility.

Q: What is the significance of the switching frequency difference?

A: The IR1152SPBF operates at fixed 66kHz, while the UCC28180D provides a programmable range of 18kHz ~ 250kHz. System design must configure the UCC28180D to operate at or near 66kHz through appropriate frequency-setting components to maintain equivalent electromagnetic interference characteristics and power stage performance.

Q: Why is the IR1152SPBF classified as obsolete?

A: Obsolete classification indicates the manufacturer has discontinued production and support. The UCC28180D, with active product status, provides continuity for new designs and ongoing system support with established supply availability.

Q: What are the implications of the moisture sensitivity level difference?

A: The IR1152SPBF carries MSL 2 (1 Year) rating, requiring controlled storage conditions with annual reflow capability. The UCC28180D's MSL 1 (Unlimited) rating eliminates time-based storage constraints, reducing inventory management complexity and improving shelf life.

Q: Are there any compliance or regulatory differences between these devices?

A: Both devices maintain REACH Unaffected status and EAR99 ECCN classification. The UCC28180D provides ROHS3 compliance certification, meeting current environmental regulatory requirements. Verify specific application requirements for your target market.
