Einführung
Here is a look back of the LC5500 series, a Sanken product, that acts as a switching power supply IC using quasi-resonant topology. This device is intended to be employed for input capacitorless applications, and making it possible for systems to comply with the harmonics standard (IEC61000-3-2 class C). It incorporates separate controller and power MOSFET chips. The controller adapts the average current control method for realizing high power factors, and the quasi-resonant topology contributes to high efficiency and low EMI noise. The series is housed in either DIP8 or TO-220F-7L (Sanken designator: FMY207) packages, depending on output power capability. The rich set of protection features helps to realize low component counts, and high performance-to-cost power supply.
