LT8335 2 A Boost/SEPIC/Inverting DC/DC Converter

Linear Technology’s DC/DC converters for battery, handheld, and telecom applications

Image of Linear Tech's LT8335 DC/DC ConverterLinear Technology/Analog Devices' LT8335 is a boost, SEPIC, or inverting DC/DC converter consuming as low as 6 μA of quiescent current. This converter is capable of generating either positive or negative output voltages using a single feedback pin. It can be configured as low ripple Burst Mode® operation maintains high efficiency down to very low output currents while keeping the output ripple below 15 mV in a typical application. The internally compensated current mode architecture results in stable operation over a wide range of input and output voltages. Integrated soft-start and frequency foldback functions are included to control inductor current during start-up. The 2 MHz operation combined with the small 8-lead DFN package that has a temperature range of +40°C to +125°C (TJ). The LT8335 is ideal for battery, handheld, and telecom applications.
