2pcs LT8619EDD 60V 1.2A Synchronous Monolithic Buck Regulator IC

Tape and Reel sealed

Product Description

The LT®8619 is a compact, high efficiency, high speed

synchronous monolithic step-down switching regulator

that consumes only 6μA of quiescent current. The LT8619

can deliver 1.2A of continuous current. Top and bottom

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

to 10mVP-P. A SYNC pin allows forced continuous mode

operation synchronized 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 LT8619, reducing the input

supply current to below 0.6μA. The PG flag signals when

VOUT is within ±7.5% of the programmed output voltage.

The LT8619 is available in a small 16-lead MSOP and

10-lead 3mm × 3mm DFN packages with exposed pad

for low thermal resistance.
