LM3578A - Switching Regulator

Download the LM3578A datasheet PDF. This datasheet also covers the LM3 variant, as both devices belong to the same switching regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM1578A is a switching regulator which can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost, and inverting configurations.

Key Features

  • a unique comparator input stage which not only has separate pins for both the inverting and non-inverting inputs, but also provides an internal 1.0V reference to each input, thereby simplifying circuit design and p. c. board layout. The output can switch up to 750 mA and has output pins for its collector and emitter to promote design flexibility. An external current limit terminal may be referenced to either the ground or the Vin terminal, depending upon the.
