AC DC Converters, Offline Switchers Procurement Notes

Verify RoHS compliance status carefully as some sources indicate non-compliance or lead-containing variants for this specific part number. Confirm the exact revision level against the latest onsemi datasheet to ensure pinout and electrical characteristics match the design requirements. Check for obsolescence notices as distribution channels may list varying lifecycle statuses.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs prioritizing low standby power and simplified feedback loops without auxiliary windings. Ensure the application requires a fixed 100 kHz frequency and fits within the 250 mA drive limit. Compare against the NCP1200A series if reduced optocoupler current or increased drive capability is necessary for the specific transformer design.

AC DC Converters, Offline Switchers Part Context

This part belongs to the NCP1200 series from onsemi, representing a generation of PWM controllers that simplify offline converter design. It utilizes current-mode control to reduce acoustic noise and allows for pulse-by-pulse current limiting. The series is noted for enabling complete offline solutions with very few external components.
