LM3478MA/MAX SOIC-8 DC-DC converter
Units Sold: 1
Spare IC LM3478 DC-DC converter, Power Supply For Nixie Clock Tubes 12V to 180V
SOIC-8
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 100
kHz and 1 MHz by using a single external resistor.

The LM3478 is a versatile Low-Side N-Channel MOSFET controller for switching regulators. It is

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 100
kHz and 1 MHz 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 5 µA and allows power supply sequencing. Internal soft-start limits the
inrush current at start-up.
