Description

The LT®8335 is a current mode DC/DC converter capableof generating either positive or negative output voltagesusing a single feedback pin. It can be configured as aboost, SEPIC or inverting converter consuming as low as6µA of quiescent current. Low ripple Burst Mode operationmaintains high efficiency down to very low outputcurrents while keeping the output ripple below 15mV ina typical application. The internally compensated currentmode architecture results in stable operation over a widerange of input and output voltages. Integrated soft-startand frequency foldback functions are included to controlinductor current during start-up. The 2MHz operationcombined with the small 8-lead DFN package, enableslow cost, area efficient solutions
