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 LT8607 reducing the input supply current to 1µA.
The MSOP package includes a SYNC pin to synchronize to an external clock, or to select Burst Mode operation or pulse-skipping with or without spread spectrum; the TR/SS pin programs soft-start or tracking.
The DFN package omits these pins and can be purchased in pulseskipping or Burst Mode operation.
