LT3757IMSE#PBF Product Details
DESCRIPTION:
The LT®3757/LT3757IMSE#PBF are wide input range, current mode, DC/DC controllers which are capable of generating either positive or negative output voltages. They can be configured as either a boost, flyback, SEPIC or inverting converter. The LT3757/LT3757IMSE#PBF drive a low side external N-channel power MOSFET from an internal regulated 7.2V supply. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages. The operating frequency of LT3757/LT3757IMSE#PBF can be set with an external resistor over a 100kHz to 1MHz range, and can be synchronized to an external clock using the SYNC pin. A low minimum operating supply voltage of 2.9V, and a low shutdown quiescent current of less than 1μA, make the LT3757/LT3757IMSE#PBF ideally suited for batteryoperated systems. The LT3757/LT3757IMSE#PBF feature soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit. The LT3757IMSE#PBF has improved load transient performance compared to the LT3757.
