LT8604

High Efficiency 42V/120mA

Synchronous Buck

FEATURES

DESCRIPTION

The LT^®8604 is a compact, high speed synchronous

monolithic step-down switching regulator that delivers up

to 120mA with high efficiency at constant switching fre-

quency, even up to 2.2MHz. It accepts a wide input voltage

range up to 42V, and consumes only 2.5µA of quiescent

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

Additional features provide for flexible and robust opera-

tion. Internal compensation with peak current mode topol-

ogy 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

V_INunder voltage lockout or to shut down the LT8604

provides additional protection. The LT8604 is available in

a small 10-Lead 3mm × 2mm DFN package with exposed

pad for low thermal resistance.
