Quick Detail:

 

High Efficiency Low-Side N-Channel Controller for Switching Regulator

 

 

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 current limiting.

Output current can be programmed with a single external

resistor.

The LM3478 has built in features such as thermal shutdown,

short-circuit protection, over voltage protection, etc. Power

saving shutdown mode reduces the total supply current to

5μA and allows power supply sequencing. Internal soft-start

limits the inrush current at start-up.
