LM3478/LM3478Q High Efficiency Low-Side N-Channel Controller for Switching Regulator LM3478/LM3478Q May 25, 2011 High Efficiency Low-Side N-Channel Controller for Switching Regulator General Description The LM3478 is a versatile Low-Side N-Channel MOSFET controller for switching regulators. It is suitable for use in topologies requiring a low side MOSFET, such as boost, flyback, SEPIC, etc. Moreover, the LM3478 can be operated at extremely high switching frequency in order to reduce the overall solution size. The switching frequency of the LM3478 can be adjusted to any value between 100kHz and 1MHz by using a single external resistor. Current mode control provides superior bandwidth...
