LM5574-Q1 Datasheet 0.5a Step-down Switching Regulator

Manufacturer: Texas Instruments

Overview: LM5574, LM5574-Q1 www.ti.com SNVS478F – JANUARY 2007 – REVISED APRIL 2013 LM5574/LM5574-Q1 SIMPLE SWITCHER® 75V, 0.

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

General Description

The LM5574 is an easy to use SIMPLE SWITCHER® buck regulator which allows design engineers to design and optimize a robust power supply using a minimum set of components.

Operating with an input voltage range of 6 - 75V, the LM5574 delivers 0.5A of continuous output current with an integrated 750mΩ N-Channel MOSFET.

The regulator utilizes an Emulated Current Mode architecture which provides inherent line regulation, tight load transient response, and ease of loop compensation without the usual limitation of low-duty cycles associated with current mode regulators.
