LM5575 Datasheet 1.5a Step-down Switching Regulator

Manufacturer: Texas Instruments

Overview: LM5575 www.ti.com SNVS471G – JANUARY 2007 – REVISED APRIL 2013 LM5575/LM5575Q SIMPLE SWITCHER® 75V, 1.

General Description

The LM5575 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 LM5575 delivers 1.5A of continuous output current with an integrated 330mΩ 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.
