The LT3724EFE#TRPBF from Analog Devices is a current-mode switching regulator controller that handles buck, boost, and SEPIC topologies from a single part. It drives an external N-channel MOSFET at a fixed 200 kHz switching frequency, covering input rails from 4 V up to 60 V. The controller outputs a positive or negative regulated voltage — useful when the same board design must support inverting or non-inverting rails. Rated for junction temperatures from -40°C to 125°C, it fits into automotive under-hood, industrial motor-drive, and outdoor telecom power stages where ambient heat is a given.
200 kHz fixed switching — what it means on the bench
The 200 kHz switching rate is fixed — no external sync, no frequency foldback. That simplifies the magnetics design because the inductor and transformer values are predictable.
Wide input range — 4 V to 60 V
The 4 V to 60 V supply range covers most unregulated DC buses. The 60 V upper limit means the controller itself survives transients without a pre-regulator.
Package and rework — 16-TSSOP with exposed pad
The 16-TSSOP-EP package has an exposed pad underneath that must be soldered to a thermal land on the PCB. That pad is the main heat path out of the controller.
