LM3478 High Efficiency Low-Side N-Channel Controller for Switching
Regulator
General Description
The LM3478 is a versatile Low-Side N-FET switching
regulator controller.
It is suitable for use in topologies requiring low side FET, 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 LM3478 can be adjusted to any value between 100kHz and 1MHz by using a single external resistor.
Current mode control provides superior bandwidth and transient response, besides cycle-by-cycle curr...
