LM3478Q Datasheet High Efficiency Low-side N-channel Controller

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM3478/LM3478Q High Efficiency Low-Side N-Channel Controller for Switching Regulator LM3478/LM3478Q May 25, 2011 High Efficiency Low-Side N-Channel Controller for Switching Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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.

Key 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. Key Specifications.
  • Wide supply voltage range of 2.97V to 40V.
  • 100kHz to 1MHz Adjustable clock frequency.
  • ±2.5% (over temperature) internal reference.
  • 10µA shutdown current (over temperature) Features.
  • LM3478Q in MSOP-8 package is.
