TOP250Y of integrated circuits based on the SMPS PCB Power Integrations schema files are also engaged in the production of other models can be used free design TOP250Y and detailed information
1: Practical arrangements for the replacement of discrete components: TOPSwitch provides greater reliability and smaller size than the scheme on discrete components. MOSFET- EMI. The special scheme of management power MOSFET-transistor reduces EMI.
2: Increased efficiency scheme with the transformer output to 90%: Fitted scheme “soft launch” and the current limitation reduces static losses; quick MOSFET-transistor dynamic reduces losses; MOSFET drivers consumption does not exceed 6 MW; limiting factor fill scheme minimizes loss of conductivity.
TOP250Y Switch Mode Power Supply Project
3: Simplification of development: simply built into most schemes; combined scheme controller and power MOSFET-transistor in the hull TO-220; all service functions are set by one external capacitor.
4: The high degree of protection: automatic restart and cyclic protection from overloading; built thermal protection.
5: Flexibility and multifunctionality: implements the functions of lowering the DC-DC converter
converter, power factor corrector; easily consistent with optical and transformer feedback devices.
