Linear Technology Corporation announces the LT8331, a current mode step-up DC/DC converter with an internal 500mA, 140V switch. It operates from an input voltage range of 4.5V to 100V, making it suitable for use with a wide range of input sources found in industrial, transportation and avionic applications. The LT8331 can be configured as either a boost, SEPIC, flyback or inverting converter. Its switching frequency is programmable from 100kHz to 500kHz, enabling designers to minimize external component sizes. Burst Mode® operation reduces quiescent current to only 6µA while keeping output ripple below 20mVP-P. The combination of a high voltage MSOP-16E package and tiny externals ensures a very compact footprint while minimizing solution cost.
