3 Description
The LM3481 device is a versatile Low-Side N-FET
high-performance controller for switching regulators.
The device is designed for use in Boost, SEPIC and
Flyback converters and topologies requiring a lowside
FET as the primary switch. The LM3481 device
can be operated at very high switching frequencies to
reduce the overall solution size. The switching
frequency of the LM3481 device can be adjusted to
any value between 100kHz and 1MHz by using a
single external resistor or by synchronizing it to an
external clock. Current mode control provides
superior bandwidth and transient response in addition
to cycle-by-cycle current limiting. Current limit can be
programmed with a single external resistor.
