DESCRIPTION

The EV8843-G-00A is used for demonstrating

the performance of MP8843, a highly integrated,

high

frequency,

synchronous,

step-down

MP8843 supports up to 3A current from a wide

input supply range of 2.5V to 6V with excellent

load and line regulation. Constant-on-time

(COT) control provides fast transient response,

high light-load efficiency and easy loop

communication interface speed up to 3.4Mbps.

It controls the output voltage on the fly from

0.6V to 1.1V with 3.9mV voltage steps and it

also controls the output voltage transition slew

rate. The interface also allows for the selection

of

power-save

mode

to

meet

different

application requirements. Protection features

include

internal

soft-start,

over-current

protection, and over-temperature protection.

MP8843 is available in 2mmx2mm 12-pin QFN

package.
