ICE1PCS01HKLA1

Overview

The ICE1PCS01HKLA1 is a standalone Power Factor Correction (PFC) controller IC designed for operation in Continuous Conduction Mode (CCM). Manufactured by Infineon Technologies, this component utilizes BiCMOS technology to achieve high efficiency across wide input voltage ranges. It features an integrated oscillator with a switching frequency of 133 kHz and operates within a supply voltage range of 10.2 V to 21 V. The device supports a maximum supply current of 100 µA during startup and functions reliably within an operating temperature range of -40°C to 125°C.

Feature Summary

• Integrated CCM PFC control logic optimized for active power factor correction converters
• Wide input voltage operational range supporting diverse AC-DC power conversion applications
• Built-in protection mechanisms including overvoltage and undervoltage detection

Applications

• Standalone active power factor correction stages in AC-DC power supplies
• Server and telecom power system front-end PFC circuits
• General purpose switched-mode power supply (SMPS) designs requiring CCM operation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix HKLA1 corresponds to the required 8-DIP package variant. Check for obsolescence status as indicated by available records. Ensure compliance with relevant environmental standards such as RoHS before integration into final assemblies.

Selection Notes

Select this component when a dedicated CCM PFC controller is required for off-line applications. Consider the 8-pin DIP package constraint for through-hole assembly requirements. Evaluate the 133 kHz fixed frequency against EMI constraints. Compare against newer generations like the ICE2PCS01 series if surface mount options or updated features are preferred.

Part Context

This part belongs to the ICE1PCS01 family of PFC controllers from Infineon. These devices are engineered for cost-effective, high-performance power factor correction. The family typically targets universal input AC-DC converters, providing robust control loops and protection features essential for meeting regulatory efficiency and harmonic distortion standards in consumer and industrial electronics.

Replacement Considerations

The ICE2PCS01GXUMA1 is identified as a similar replacement option. Verify pin compatibility and electrical parameter alignment before substitution.
