Analog Devices 65V, 2A Synchronous Step-Down Regulator with 2.5µA Quiescent Current, Part #: LT8620EMSE#PBF | DEX is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that accepts a wide input voltage range up to 65V, and consumesonly 2.5µAofquiescent current. Topandbottom power switches are included with all necessary circuitry to minimize the need for external components. Low ripple Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. A SYNC pin allows synchronization to an external clock. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability. The EN/UV pin has an accurate 1V threshold and can be used to programVIN undervoltage lockout orto shut down the LT8620 reducing the input supply current to 1µA. A capacitor on the TR/SS pin programs the output voltage ramp rate during start-up. The PG flag signals when VOUT iswithin ±9% ofthe programmed output voltage aswell as fault conditions. The LT8620 is available in small 16-Lead MSOP and 3mm× 5mmQFNpackageswith exposed pads for low thermal resistance.
