LM3481 High Efficiency Low-Side N-Channel Controller for Switching Regulators November 16, 2007 LM3481 High Efficiency Low-Side N-Channel Controller for Switching Regulators General Description The LM3481 is a versatile Low-Side N-FET high performance controller for switching regulators. It is suitable for use in topologies requiring a low-side FET, such as boost, flyback, SEPIC, etc. The LM3481 can be operated at extremely high switching frequencies in order to reduce the overall solution .. size. The switching frequency of the LM3481 can be adjusted to any value between 100 kHz and 1 MHz by using a single external resistor or by synchronizing it to an external clock....
