Details

The μPFC IR1153 power factor correction IC, based on IR proprietary "One Cycle Control" (OCC) technique, provides for high PF, low THD and excellent DC Bus regulation while enabling drastic reduction in component count, PCB area and design time as compared to traditional solutions. The IC is designed to operate in continuous conduction mode Boost PFC converters with average current mode control at a fixed 22.2kHz switching frequency. The IR1153 features include input-line sensed brown-out protection, dedicated pin for over voltage protection, cycle by cycle peak current limit, open loop protection, VCC UVLO, soft start and micropower startup current of less than 75µA. In addition, for standby power requirements, the IC can be driven into a micropower sleep mode by pulling the OVP/EN pin low where the current consumption is less than 75uA. IR1153 is available in SO-8 package.Features • PFC IC with IR proprietary “One Cycle Control” • Continuous conduction mode boost type PFC • Fixed 22.2kHz switching frequency • Average current mode control • Input line sensed brownout protection • Output overvoltage protection • Open loop protection • Cycle by cycle peak current limit • VCC under voltage lockout • Programmable soft start • Micropower startup • User initiated micropower “Sleep Mode” • 750mA peak gate drive • Latch immunity and ESD protection

FAQs

What is IR1153S?

The IR1153S is a high-performance synchronous buck converter IC (Integrated Circuit) manufactured by Infineon Technologies. It is designed for high-efficiency power conversion in various applications, including power supplies, consumer electronics, and industrial equipment.

How Does IR1153S Work?

The IR1153S operates as a synchronous buck converter, converting higher input voltage to a lower output voltage efficiently. It regulates the output voltage by controlling the duty cycle of the internal switches and adjusting the conversion ratio based on feedback information. The IC includes protection features such as overcurrent and overtemperature protection for reliable operation.

How Many Pins does IR1153S have and What are the Functions of the Pinout Configuration?

The IR1153S is typically available in a compact package like SO-8 or DSO-8. The pinout configuration includes:

  • VIN: Input voltage pin.
  • GND: Ground pin.
  • SW: Switching node output pin.
  • FB: Feedback pin for output voltage regulation.
  • SS/TR: Soft-start/Tracking function pin.
  • VCC: Power supply pin for internal IC circuits.
  • PGND: Power ground pin for internal IC circuits.

What are the Pros and Cons of IR1153S?

Pros:

  • High Efficiency: Achieves high conversion efficiency, reducing power loss.
  • High Performance: Provides reliable power conversion with excellent regulation.
  • Integrated Protection Features: Includes overcurrent and overtemperature protection for system reliability.
  • Compact Package: Available in a compact and space-saving package for easy integration.

Cons:

  • Complexity: Requires understanding of buck converter operation and external component selection for optimal performance.
  • Thermal Considerations: Proper thermal management may be necessary for high-power applications.
  • External Components: Some applications may require additional external components for specific functions or protections.

Are There Any Equivalents/Alternatives to IR1153S for Recommendation?

  • Alternatives to the IR1153S include the LM22677 from Texas Instruments and the LT8610 from Analog Devices, both offering synchronous buck converter functionality.
  • Another alternative is the MP24890 from Monolithic Power Systems, which also provides similar buck converter features.
