TDA48632XKLA1

Overview

The TDA48632XKLA1 is a power factor correction (PFC) controller manufactured by Infineon Technologies. It operates in discontinuous conduction mode (DCM) and controls a boost converter to draw sinusoidal current from single-phase line supplies while stabilizing DC voltage. The component is housed in an 8-pin PDIP package and supports through-hole mounting. It functions within a temperature range of -40°C to +150°C and draws a working supply current of 20 µA. This part is classified under PMIC - Power Management ICs.

Feature Summary

• Controls boost converters for single-phase AC-DC conversion
• Operates in discontinuous conduction mode (DCM)
• Ensures sinusoidal input current and stabilized DC output voltage

Applications

• Single-phase AC-DC power supplies
• High power factor applications
• Low THD (Total Harmonic Distortion) power systems

Procurement Notes

Verify the exact suffix and package type against official Infineon documentation, as variations exist within the TDA4863 family. Confirm the component status, as this specific part number may be discontinued or subject to limited availability. Ensure compatibility with existing PCB footprints for DIP-8 packages before procurement.

Selection Notes

Select this component for designs requiring simple DCM PFC control in single-phase applications. Consider the operating temperature range and through-hole packaging requirements. Verify that the 20 µA supply current meets the system's standby power constraints. Check for alternative active parts if discontinuation impacts long-term production plans.

Part Context

The TDA4863 series includes variants such as TDA4863HKLA1 and TDA4863-2. These components are designed for cost-effective power factor correction in consumer and industrial electronics. The TDA48632XKLA1 specifically denotes the PDIP-8 package variant within this family, focusing on basic DCM operation without complex digital interfaces.
