Description

This design is driven by the LM3481. The LM3481 is a versatile Low-Side N-FET high performance controller for switching regulators. The switching frequency of the LM3481 can be adjusted to any value between 100 kHz and 1 MHz by using a single external resistor or by synchronizing it to an external clock. The LM3481 has built in protection features such as thermal shutdown: short-circuit protection and over voltage protection. Power saving shutdown mode reduces the total supply current to 5µA and allows power supply sequencing.
