ANALOG DEVICES LT8606IMSE#TRPBF Switching Regulator, Buck, 2MHz, 3V to 42V Input, 1.8V to 12V Output, 350mA, Adjustable, MSOP-EP-10

LT8606IMSE#TRPBF is a compact, high-efficiency, high-speed synchronous monolithic step-down switching regulator that consumes only 1.7µA of non-switching quiescent current. It can deliver 350mA of continuous current. Low-ripple Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. 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 program VIN undervoltage lockout or to shut down the device. The PG pin signals when VOUT is within ±8.5% of the programmed output voltage as well as fault conditions. Applications include general-purpose step-down converter, low-EMI step-down.
