IR1150STR

Overview

The IR1150STR is a Power Factor Correction (PFC) controller integrated circuit manufactured by Infineon Technologies. It operates in Continuous Conduction Mode (CCM) and supports a switching frequency of 200kHz. The device requires a supply voltage range of 15V to 20V and draws a startup current of 175µA. It is housed in an 8-SOIC package with a width of 3.90mm and is designed for surface mount mounting. The component functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports continuous conduction mode (CCM) operation for power factor correction applications.
• Integrated MOSFET gate driver output capability.

Applications

• Desktop Switching Mode Power Supplies (SMPS)
• Server SMPS
• AC-DC Adapters

Procurement Notes

Verify the obsolete part status before procurement planning, as availability may be limited to existing stock or last-time buys. Confirm that the 8-SOIC package dimensions align with PCB footprint requirements. Ensure the 15V to 20V supply voltage range matches the target application's VCC design. Validate that the 0°C to 70°C operating temperature range meets environmental specifications. Check for any specific handling instructions related to its surface mount configuration.

Selection Notes

Select this component for designs requiring CCM PFC control at 200kHz. Ensure the application environment stays within the 0°C to 70°C operational limits. Verify compatibility with the 8-SOIC surface mount package constraints. Confirm that the system can provide the required 15V to 20V supply voltage. Consider the 175µA startup current when designing the bias circuitry.

Part Context

The IR1150STR belongs to the IR1150S base product line from Infineon Technologies. It is categorized under Integrated Circuits (ICs) within the Power Management ICs (PMIC) subcategory. The device is specifically designated for Power Factor Correction (PFC) functions. Its packaging is listed as Cut Tape (CT), indicating it is supplied in tape-and-reel format for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the part status is marked Obsolete, alternative sourcing should focus on authorized distributors holding remaining inventory or verified equivalent components from other manufacturers meeting identical electrical and mechanical specifications.
