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.

Key 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 compensation. An intelligent current lim.
