Low IQ Boost Regulator Evaluation Board – LT®8365 is a boost converter. It operates with a switching frequency of 400kHz and is designed to convert a 9V to 30V source to 250V, with 10mA output current. The demo board contains an optional third charge pump stage for applications requiring higher output voltages. If needed, remove R14 and install optional components. Output voltage sensing connections remain the same. The LT8365 can be used for different topologies with input voltages up to 60V. However, component selection in this demo circuit restricts the input voltage to 30V.
