LT8335IDDB#TRMPBF

直流/直流开关稳压器, 反相, SEPIC稳压器, 可调, 3V-25V输入, 28V输出, 2A, DFN-8

The is a low IQ boost/SEPIC/inverting converter with 2A, 28V switch in 8 pin DFN package. The LT8335 uses a fixed frequency, current mode control scheme to provide excellent line and load regulation. This is a current mode DC/DC converter capable of generating either positive or negative output voltages using a single feedback pin. It can be configured as a boost, SEPIC or inverting converter consuming as low as 6µA of quiescent current. Low ripple burst mode operation maintains high efficiency down to very low output currents while keeping the output ripple below 15mV 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. It is used in telecom field.
