LT8613EUDE#TRPBF

LT8613 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. The built-in current sense amplifier with monitor and control pins allows accurate input or output current regulation and limiting. 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 program VIN undervoltage lockout or to shut down the device reducing the input supply current to 1µA. It is used in application such as automotive and industrial supplies, general purpose step-down, CCCV power supplies etc.
