Power Integrations TOP250YN AC-DC Offline Switcher IC

TOP250YN integrated AC-DC switcher IC with a high-voltage MOSFET, PWM control, fault protection and selectable 132 kHz or 66 kHz switching.

The TOP250YN is an AC-DC offline switcher for flyback power supply designs. It combines a high-voltage MOSFET, PWM control and fault protection in one IC. You can select 132 kHz or 66 kHz switching to suit the design.
Integrated soft-start eases startup stress. Cycle-by-cycle current limiting and line under-voltage and over-voltage functions help manage power supply faults. Hysteretic thermal shutdown supports automatic recovery after the device cools, and frequency jittering helps reduce EMI.
Use it in offline flyback power supplies, AC-DC adapters, printer power supplies and multiple-output supplies for set-top boxes or cable decoders. Its combined switching and control functions support a range of power supply designs.
