AC DC Converters, Offline Switchers Applications

• Offline flyback power supplies
• Universal input AC-DC converters

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix (e.g., GN vs. PG) to ensure correct packaging type, as the GN variant typically uses cut tape or reel while others may use tubes. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region and stock levels change frequently.

AC DC Converters, Offline Switchers Selection Notes

Select this component for low-power applications requiring universal AC input compatibility. Ensure the design accommodates the 132 kHz switching frequency and thermal requirements up to 150 °C. Verify that the 700 V breakdown voltage meets the isolation and surge protection needs of the target application circuit.

AC DC Converters, Offline Switchers Part Context

Part of the TinySwitch-II family, which combines high-voltage MOSFETs with intelligent control logic for efficient offline conversion. This series targets cost-sensitive, low-power designs where board space is limited and high integration reduces external component count.
