Description

The LT®8607 is a compact, high efficiency, high speed syn-chronous monolithic step-down switching regulator that consumes only 1.7µA of non-switching quiescent current. The LT8607 can deliver 750mA of continuous current. 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 LT8607reducing the input supply current to 1µA.
