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.
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
That pad is the main heat path out of the controller.
