DESCRIPTION
The LT®3757 is a wide input range, current mode, DC/DC controller which is capable of generating either positive or negative output voltages. It can be configured as either a boost, flyback, SEPIC or inverting converter. A low minimum operating supply voltage of 2.9V, and a low shutdown quiescent current of less than 1μA, make the LT3757 ideally suited for battery-operated systems. The LT3757 features soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit. The device is available in a small 10-lead DFN (3mm × 3mm) or MSOP package. L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
