The synchronous rectifier means you skip the external catch diode — the internal low-side switch handles it, which keeps the BOM short and the efficiency curve flatter across the load range. Switching frequency is programmable from 300 kHz to 2.2 MHz, letting you trade inductor size against ripple. The 16-MSOP-EP package with exposed pad needs a solid thermal via pattern under the pad to pull heat out at 1.2 A continuous — treat that pad as a mandatory connection, not optional. ## Sourcing and lifecycle — active part, standard channel The LT8619EMSE#PBF carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy or obsolescence risk for new designs — it is a current-production part from Analog Devices.","metaTitle":"LT8619EMSE#PBF Buck Regulator, 3 V to 60 V Input, 1.2 A","metaDescription":"LT8619EMSE#PBF step-down regulator from Analog Devices. 3 V to 60 V input, 1.2 A output, adjustable down to 0.8 V.
