2.0A,100V High Efficiency synchronous Step-Down DC/DC Converter
Description
HM1588 is a high efficiency Z monolithic synchronous step-down DC/DC converter utilizing a constant frequency, average current mode control architecture. Capable of delivering up to 1.5A continuous load with excellent line and load regulation. The device operates from an input voltage range of 8.5V to 100 V and provides an adjustable output voltage from 1.0V to 60V.
The HM1588 Features short circuit and thermal protection circuits to increase system reliability. The internal soft-start avoids input inrush current during startup.
The HM1588 require a minimum number of external ponents. and a wide array of protection Features to enhance reliability
