DESCRIPTION

The

MPQ9840

is

a

high-frequency,

synchronous, rectified, step-down, switch-mode

converter with built-in power MOSFETs. It

offers a very compact solution that achieves

3.5A of continuous output current with excellent

load and line regulation over a wide 3.3V to 36V

input supply range. The switching frequency

can be programmed or synchronized to an

external clock in the range of 350kHz to

2.5MHz. The synchronous operation and ultra-

low 14μA sleep mode quiescent current provide

high efficiency over the output current load

range, allowing the MPQ9840 to be used in a

variety of step-down applications in automotive

input

environments

and

battery-powered

applications.

Peak-current-mode operation provides fast

transient response and eases loop stabilization.

The excellent low dropout performance allows

the MPQ9840 to be used in high duty cycle

applications.

Full protection features include over-current

protection (OCP), short-circuit protection (SCP),

and thermal shutdown. An open-drain power

good (PG) signal indicates when the output is

within 10% of its nominal voltage.

The MPQ9840 is available in a space-saving

QFN-16 (3mmx4mm) package.
