AC DC Converters, Offline Switchers Procurement Notes

Verify the specific ordering suffix KLA1 against official Infineon documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the PG-DIP-7 through-hole package aligns with your assembly requirements. Cross-reference the RoHS compliance status directly with the manufacturer's certificate rather than relying on distributor summaries. Ensure the part number matches the exact generation and variant intended for your design.

AC DC Converters, Offline Switchers Selection Notes

Select this component when designing non-isolated or isolated converters requiring integrated high-voltage startup and fixed-frequency control. The internal 800 V MOSFET simplifies bill-of-materials by eliminating external switching devices. Consider the 65 kHz frequency for balancing efficiency and EMI. Verify thermal management capabilities given the 150 °C junction temperature rating and the DIP-7 package constraints.

AC DC Converters, Offline Switchers Part Context

This part belongs to the fifth-generation CoolSET™ family, which combines a power MOSFET with a sophisticated PWM controller. The ICE5BR series specifically targets cost-effective solutions for medium-power applications.
