Product Summary

The 203D6 is a PWM Current-Mode Controller for Universal Off-Line Supplies Featuring Standby and Short Circuit Protection. With an internal structure operating at a fixed 40 kHz, 60 kHz or 100 kHz switching frequency, the 203D6 features a high-voltage startup FET which ensures a clean and loss.less startup sequence. Its current-mode control naturally provides good audio.susceptibility and inherent pulse-by-pulse control. The applications of the 203D6 include AC-DC Adapters for Notebooks, etc, Offline Battery Chargers and Auxiliary Power Supplies (USB, Appliances, TVs, etc.)
