IR1153SPBF

Overview

The IR1153SPBF is a power factor correction controller from Infineon Technologies, manufactured under the International Rectifier brand. It implements the proprietary One Cycle Control technique for continuous conduction mode boost PFC applications. The device operates at a fixed switching frequency of 22.2 kHz and utilizes average current mode control to ensure high power factor and low total harmonic distortion. Key electrical specifications include a peak gate drive capability of 750 mA and a micropower startup current of less than 75 µA. The component is housed in an 8-pin SOIC package.

Feature Summary

• Implements proprietary One Cycle Control technique for high power factor and low THD
• Features input-line sensed brown-out protection and dedicated output overvoltage protection pin
• Includes cycle-by-cycle peak current limit and open loop protection mechanisms
• Supports user-initiated micropower sleep mode with current consumption below 75 µA

Applications

• Continuous conduction mode boost PFC converters
• Power supplies requiring high power factor correction
• Standby power systems utilizing micropower sleep modes

Procurement Notes

Verify the complete part number including suffixes such as SPBF or STRPBF against official datasheets to confirm packaging and tape-and-reel configurations. Confirm that the specific variant matches the required operating temperature range and package type. Ensure compatibility with the intended AC input voltage levels and DC bus regulation requirements before procurement.

Selection Notes

Select this component for designs requiring fixed-frequency operation without external clock synchronization. It is suitable for applications prioritizing reduced component count and PCB area through integrated control logic. Consider the 22.2 kHz frequency for EMI management and the availability of comprehensive protection features for robust system reliability.

Part Context

The IR1153 series belongs to the μPFC family of power factor correction controllers designed by International Rectifier, now part of Infineon Technologies. These ICs are engineered to simplify PFC design by integrating control loops and protection circuits into a single package. The technology aims to replace traditional multi-component solutions with a unified controller approach.
