ICE2PCS03HKLA1

Power Factor Correction (PFC) is an important technique for improving the quality of electricity supplied to end-customers and is widely applied in industrial and commercial electrical systems. ICE2PCS03HKLA1 is a popular integrated power factor correction (PFC) controller from Infineon Technologies. This device is used for controlling the active Power Factor Correction (PFC) and for the implementation of a quasi-resonant fly-back power-stage.

The ICE2PCS03HKLA1 provides cost-effective, Active Power Factor Correction (PFC) solutions by providing full PFC control as well as quasi-resonant fly-back power-stage control. This device also provides multiple protection functions, such as over-voltage protection, over-current protection, under-voltage protection, and thermal shutdown protection. The IC is designed to meet the requirements of the EN61000-3-2 standard for harmonic reduction for consumer and industrial applications.

The ICE2PCS03HKLA1 Application field includes AC-DC converters and transformerless power supplies, offline applications up to 400W and online applications up to 250W. Consumers and applications reliant on stabilization and noise reduction of the power supply AC to voltage level DC, many of which adhere to EN61000-3-2 standards.

The working principle is based on an integrated PFC Control Loop providing the differential error and control signals between the input voltage and current and the output voltage and current. The ICE2PCS03HKLA1 is equipped with simple circuitry with an external resistor and current sense resistance, as well as a PFC capacitor for energy storage. This IC measures the voltage and current of the input power and the output power, generating the necessary corrections signals for power factor correction.

In the ICE2PCS03HKLA1, advanced features are introduced, such as optimized PFC control, optimizing power circuit impedance for low harmonic distortion, and current peak detection for minimal drain current. It also incorporates an integrated safety block, allowing additional safety measures as required by IEC664/A: Safety Requirements for Electrical Appliances.
