ICE2PCS03XKLA1

Overview

The ICE2PCS03XKLA1 is a Power Factor Correction (PFC) controller IC manufactured by Infineon Technologies, designed for continuous conduction mode (CCM) operation. It features an integrated high-voltage startup circuit and operates within a supply voltage range of 11V to 25V. The device supports a switching frequency of 100kHz and includes brown-out detection functionality. Packaged in an 8-DIP format with a width of 7.62mm, it is rated for industrial temperatures ranging from -40°C to 125°C. The component draws a startup current of 450 µA and is classified as discontinued.

Feature Summary

• Integrated high-voltage startup circuit eliminates external start-up components
• Brown-out detection ensures reliable operation during low input voltage conditions
• Optimized for continuous conduction mode (CCM) PFC applications

Applications

• Stand-alone PFC stages in AC-DC power supplies
• Power factor correction in switch-mode power supplies (SMPS)
• Industrial power conversion systems requiring CCM control

Procurement Notes

This component is officially listed as discontinued by the manufacturer. Availability is limited to existing stock or surplus channels. Verify the specific suffix 'XKLA1' against official documentation, as datasheets primarily reference 'HKLA1' or 'GXUMA1'. Confirm end-of-life status and lead times with authorized distributors before procurement planning.

Selection Notes

Select this IC for designs requiring a standalone CCM PFC controller with integrated brown-out protection. Consider the 8-DIP package for through-hole assembly requirements. Evaluate the 100kHz switching frequency against electromagnetic interference (EMI) constraints. Compare against newer generations like the ICE2PCS02G if active sourcing is required.

Part Context

The ICE2PCS03 belongs to Infineon's family of PFC controllers designed for universal input applications. It complements other variants such as the ICE2PCS01G and ICE2PCS02G, offering specific feature sets like brown-out detection. The part is intended for use in offline power supplies where high power factor and low harmonic distortion are critical performance metrics.

Replacement Considerations

The ICE2PCS03GXUMA1 is documented as a similar replacement option. Verify pin compatibility and electrical specifications against the original design requirements when substituting.
