MP2172GJ集成电路（IC）稳压器-DC-DC开关稳压器规格书PDF中文资料

DESCRIPTION

The MP2172 is a monolithic, step-down, switchmode

converter with integrated, internal, power

MOSFETs. The MP2172 can achieve up to 2A

of continuous output current from a 2.5V to

5.5V input voltage with excellent load and line

regulation. The output voltage can be regulated

as low as 0.6V.

Constant-on-time (COT) control provides fast

transient response and eases loop stabilization.

Full protection features include cycle-by-cycle

current limiting and thermal shutdown.

The MP2172 is ideal for a wide range of

applications, including automotive infotainment,

clusters, telematics, and portable instruments.

The MP2172 requires only a minimal number of

readily available, standard, external

components and is available in a small

TSOT23-8 package.
