LM5574 Step-Down Switching Regulator

LM5574 Description

www.DataSheet4U.com LM5574 75V, 0.5A Step-Down Switching Regulator January 2007 LM5574 75V, 0.5A Step-Down Switching Regulator General .
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 minimu.

LM5574 Features

* Integrated 75V, 750mΩ N-channel MOSFET Ultra-wide input voltage range from 6V to 75V Adjustable output voltage as low as 1.225V 1.5% feedback reference accuracy Operating frequency adjustable between 50kHz and 500kHz with single resistor Ma

LM5574 Applications

* where the output may be precharged before the LM5574 is enabled. An internal precharge MOSFET is turned on for 250ns each cycle just prior to the on-time interval of the buck switch. An external capacitor is required between the BST and the SW pins. A 0.022µF ceramic capacitor is recommended. The ca
