The LT8331 is 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 20mV. The combination of a high voltage MSOP-16E package and tiny externals ensures a very compact footprint while minimizing solution cost.
