ICE1CS02GXUMA1

Overview

The ICE1CS02GXUMA1 is a discontinuation-confirmed Power Factor Correction (PFC) integrated circuit from Infineon Technologies, belonging to the ICE1CS02 series. It functions as an AC/DC converter controller designed for continuous conduction mode (CCM) applications. The component utilizes a PG-DSO-8 surface-mount package and operates within a supply voltage range of 11V to 25V. It features a fixed switching frequency of 65kHz and supports a maximum duty cycle of 80%. The device is rated for operation across a temperature range of -40°C to +125°C. Key electrical parameters include a startup current of 450µA and a working supply current of 900µA. The unit weighs approximately 8 units and is classified under PMIC power management ICs.

Feature Summary

• Integrated input brown-out protection for reliable operation during voltage sags
• Continuous conduction mode (CCM) control architecture for stable power factor correction
• Fixed frequency switching operation to simplify electromagnetic interference filtering

Applications

• Power factor correction stages in AC/DC switched-mode power supplies
• Industrial power conversion systems requiring CCM topology
• Consumer electronics adapters with strict efficiency standards

Procurement Notes

This component is officially marked as End-of-Life (EOL) by the manufacturer. Distribution channels indicate that Mouser does not currently stock this item in the specified region. Verification of availability through alternative distributors or authorized agents is required before procurement planning. Supply chain stability cannot be guaranteed due to the discontinued status.

Selection Notes

Engineers should evaluate the discontinuation status when selecting this part for new designs. The fixed 65kHz frequency and CCM operation define its performance envelope. Alternative components must match the PG-DSO-8 footprint and 11V-25V operating range. Compatibility with existing PCB layouts and thermal management solutions remains critical for any substitution strategy.

Part Context

The ICE1CS02GXUMA1 is part of the broader ICE1CS02 family of PFC controllers. It shares architectural similarities with other CCM PFC ICs but is distinguished by its specific brown-out protection features and fixed-frequency operation. The 'GXUMA1' suffix denotes the tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers must identify equivalent CCM PFC controllers with compatible pinouts and electrical specifications. Cross-reference with active Infineon PFC families or third-party equivalents is necessary.
