That 100 V input ceiling means it can regulate from a 48 V telecom bus or a 72 V nominal industrial rail without an external pre-regulator. ## Switching frequency and control-loop flexibility The oscillator runs from 100 kHz to 1 MHz, programmable with a single resistor on the RT pin. Clock sync input is available, so the switcher can lock to a system clock and avoid beat-frequency coupling with a downstream converter or a sensitive ADC sampling clock. Control features include an enable pin for sequencing, frequency control for spread-spectrum or EMI mitigation, and a soft-start pin that ramps the reference voltage — this prevents inrush current overshoot on a heavily loaded output at power-up. The controller is RoHS3 compliant and ships in a tube. The 0.118-inch body width (3.00 mm) fits a compact layout; the exposed pad footprint requires a thermal via array under the package for the rated power dissipation. No official second-source or pin-compatible cross-reference is recorded from the manufacturer. For a BOM that requires a hedge, the parametric space (100 V input, boost/flyback/SEPIC, 1 MHz) narrows the alternative search to controllers with the same supply range and topology set.","metaTitle":"LT3758EMSE#PBF Boost/Flyback/SEPIC Controller, 100V Input","metaDescription":"Analog Devices LT3758EMSE#PBF current-mode PWM controller.
