Overview

SM72485 SolarMagic 100V, 150 mA Constant On-Time Buck Switching Regulator May 10, 2011 SM72485 SolarMagic 100V, 150 mA Constant On-Time Buck Switching Regulator General Description The SM72485 Step Down Switching Regulator features all of the functions needed to implement a low cost, efficient, Buck bias regulator.
This high voltage regulator contains an 100 V N-Channel Buck Switch.
The device is easy to implement and is provided in the MSOP-8 and the thermally enhanced LLP-8 package.
The regulator is based on a control scheme using an ON time inversely proportional to VIN.
This feature allows the operating frequency to remain relatively constant.
The control scheme requires no loop compen...
