MPQ9842

36V, 2A, Low I_Q,

Step-Down Converter

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The

MPQ9842

high-frequency,

•

2μA Low Shutdown Supply Current

synchronous, rectified, step-down, switch-mode

converter with built-in power MOSFETs. It

offers a very compact solution that achieves 2A

of continuous output current with excellent load

and line regulation over a wide 3.3V to 36V

input supply range. The switching frequency is

programmable or can be synchronized to an

external clock in the range of 350kHz to

2.5MHz. Synchronous operation and ultra-low

14μA sleep mode quiescent current provide

high efficiency over the output current load

range, allowing the MPQ9842 to be used in a

variety of step-down applications in automotive

input environments and battery-powered

applications.

14μA No-Load Quiescent Current

Internal 125mΩ High-Side and 55mΩ Low-

Side MOSFET

350kHz to 2.5MHz Programmable Switching

Frequency

Power Good (PG) Output

External Soft Start (SS)

80ns Minimum On Time

Selectable Forced CCM and AAM

Hiccup Over-Current Protection (OCP)

AEC-Q100 Grade-1

Available in a QFN-16 (3mmx4mm)

Package

APPLICATIONS

Peak-current-mode operation provides fast

transient response and eases loop stabilization.

The excellent low dropout performance allows

the MPQ9842 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 MPQ9842 is available in a space-saving

QFN-16 (3mmx4mm) package.
