IR1153STRPBF

Overview

The IR1153STRPBF is a power factor correction (PFC) controller manufactured by Infineon Technologies, designed for continuous conduction mode (CCM) boost PFC converters. It utilizes the proprietary One Cycle Control technique to achieve high power factor and low total harmonic distortion. The device operates at a fixed switching frequency of 22.2 kHz and features average current mode control. Key electrical parameters include a micropower startup current of less than 75 µA and a peak gate drive capability of 750 mA. The component supports brown-out protection, output overvoltage protection, cycle-by-cycle peak current limit, and open-loop protection.

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 micropower sleep mode with current consumption below 75 µA

Applications

• Continuous conduction mode boost PFC converters
• AC/DC power supplies requiring high efficiency
• Standby power applications utilizing micropower sleep mode

Procurement Notes

Verify the specific package variant against the datasheet, as the suffix 'STRPBF' indicates tape and reel packaging. Confirm RoHS compliance status directly from the manufacturer's documentation. Ensure the operating temperature range aligns with system requirements, noting the specified limits. Cross-reference the part number alias SP001550848 if sourcing through alternative distributors. Validate that the fixed 22.2 kHz frequency meets the electromagnetic interference constraints of the target design.

Selection Notes

Select this component when a fixed switching frequency of 22.2 kHz is required for CCM boost topologies. It is suitable for designs prioritizing reduced component count and PCB area due to the integrated One Cycle Control architecture. Consider its micropower capabilities for applications demanding low standby consumption. Ensure the 750 mA peak gate drive current is sufficient for the external MOSFETs in the circuit. Verify compatibility with average current mode control requirements.

Part Context

The IR1153 belongs to the μPFC family of power factor correction controllers from Infineon Technologies. It is an evolution of International Rectifier's legacy PFC solutions, maintaining the core One Cycle Control functionality. The device is categorized under PMIC - Power Management ICs within the broader product portfolio. It shares architectural similarities with other CCM PFC controllers but is distinguished by its fixed frequency operation and specific protection feature set.
