ICE1QS01

Overview

The ICE1QS01GXT is a current and power monitor controller designed for low-power Power Factor Correction (PFC) applications in SMPS supplies. It operates within a supply voltage range of up to 20V. The component supports surface mount installation in a DSO-8 package. It functions with a quiescent supply current of 12.5 mA and maintains operational stability across an extended temperature range from -25°C to +150°C.

Feature Summary

• Integrated current and power monitoring capabilities for PFC regulation
• Designed specifically for low-power switching mode power supply applications
• Supports operation at elevated temperatures up to 150°C

Applications

• Low-power PFC circuits in SMPS
• Current and power monitoring controllers
• Regulator control for SMPS supplies

Procurement Notes

Verify the specific suffix 'GXT' as it denotes the tape and reel packaging configuration. Confirm that the component status is End-of-Life, as availability may be restricted or limited. Ensure compatibility with existing PCB footprints for the DSO-8 package before finalizing procurement plans.

Selection Notes

Select this component when designing low-power PFC stages requiring integrated monitoring. Verify that the 20V maximum supply voltage aligns with the system design. Consider the high operating temperature limit if thermal management is constrained. Check for alternative active components if long-term supply continuity is required.

Part Context

This part belongs to Infineon's portfolio of power management ICs focused on AC/DC conversion and PFC. It serves as a specialized controller rather than a general-purpose PWM chip, targeting efficiency improvements in low-power offline applications through precise current and power regulation.
