ISL8540 Description

® ISL8540 Data Sheet September 9, 2008 FN6495.5 DC/DC Power Switching Regulator The ISL8540 is a step down DC/DC power switching regulator which accepts 9.0V to 40V input and provides a 2A output current. The output voltage can be set in the range between 1.21V and 35V by means of an external divider. The device uses an internal power DMOS transistor with a typical rDS(ON) of 0.19Ω to obtain very high efficiency and...
