• Manufacturer Part Number: NCP1562
• Description: 300 W 80 PLUS ATX Reference Design
• Manufacturer: ONSEMI [ON Semiconductor]

NCP1653 – Compact PFC Controller
ATX Power Supplies. This device enables the inclusion of a PFC front-end into an ATX power supply by simplifying
the design through integration (reduces part count) and providing a robust, cost effective front-end without
range switches.
NCP1562 – Active Clamp Controller
the ATX Power Supply. It can be used in applications with or without the PFC front-end. Thanks to its integrated
drivers, soft-switching, and accurate duty-cycle control amongst other unique features (such as soft-stop), the
NCP1562 significantly enhances the efficiency and ruggedness of the power stage without additional cost.
NCP1027 – Standby Controller
highly integrated features and the integrated HV FET on the silicon makes it an ideal and cost-effective option.
The NCP1027 can deliver 15 W of standby power at high efficiency across the entire line conditions (85 V to
265 V AC).
NCP4330 – Post Regulator
solution for generating multiple-outputs in an ATX Power Supply. The NCP4330 can also lower the cost of the
overall solution while enabling this higher efficiency and makes it an ideal solution for achieving higher than
80% efficiencies.
