Simplify Your High Voltage DC/DC Converters to Save Battery Life

April 27, 2016 // By Luc Desimpel

Linear Technology’s LT8330 and LT8331, two Low Quiescent current Boost/SEPIC/Inverting Converters, are specifically designed for Automotive, Industrial, Telecom and Portable applications. The LT8330 has a 1A, 60V power switch and an input range of 3-40V, while the LT8331 has a 500mA, 140V power switch and an input range of 4.5-100V. Both parts have low quiescent current, a desirable feature that saves battery life. These two parts cover a wide range of applications, from very low to very high output voltage levels, and with a wide input voltage range. Both parts have low ripple burst mode operation and maintain high efficiency levels at light loads.
