LM3481 Datasheet (National Semiconductor) - High Efficiency Low-Side N-Channel Controller

LM3481, High Efficiency Low-Side N-Channel Controller

The LM3481 is a versatile Low-Side N-FET high performance controller for switching regulators.

It is suitable for use in topologies requiring a low-side FET, such as boost, flyback, SEPIC, etc.

The LM3481 can be operated at extremely high switching frequencies in order to reduce the overall solution

LM3481 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. Internal soft-start limits the inrush current at start-up. Key Specifications

* Wide supply voltage range of 2.9
