It drives an external transistor (no synchronous rectifier) and delivers a single output configurable for positive or negative polarity. The 100kHz to 1MHz switching range lets you trade inductor size against efficiency, and the clock sync input keeps multiple rails phase-aligned on dense boards. Control features include enable, frequency control, and soft start. ## Package and temperature grade for industrial and automotive use Housed in a 10-WFDFN exposed pad package (3x3 mm, DFN-10), the LT3757AIDD#PBF is surface-mount and suited for compact power stages. The exposed pad needs a solid thermal via stitch to the ground plane to keep junction temperature in check at higher switching frequencies. ## Lifecycle and sourcing posture It is ROHS3 compliant.","metaTitle":"LT3757AIDD#PBF Boost/Flyback/SEPIC Controller, 2.9V-40V","metaDescription":"LT3757AIDD#PBF current-mode PWM controller for boost, flyback, SEPIC topologies. 2.9V to 40V supply, 100kHz-1MHz switching, -40°C to 125°C.
