MPQ4418A

0.6A, 36V, High-Efficiency, Low-R_DS(ON)

Synchronous Step-Down Converter,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The

MPQ4418A

high-efficiency,

•

Wide 4V to 36V Operating Input Voltage

(V_IN) Range

Configurable Output Voltage (V_OUT) from

0.8V

Internal Low-R_DS(ON)90mΩ High-Side

MOSFET (HS-FET) and 55mΩ Low-Side

MOSFET (LS-FET)

synchronous, rectified, switch-mode, step-down

converter with built-in internal power MOSFETs.

It can achieve up to 0.6A of continuous output

current (I_OUT) across a wide input voltage (V_IN)

range (4V to 36V), with excellent load and line

regulation.

•

High-Efficiency Synchronous Mode

Operation

410kHz Default Switching Frequency (f_SW)

200kHz to 2.2MHz Synchronized External

Clock

High Duty Cycle for Automotive Cold Crank

Forced Continuous Conduction Mode

(FCCM)

Internal Soft Start (SS)

Power Good (PG)

Over-Current Protection (OCP) with Hiccup

Mode

Synchronous mode offers high efficiency across

the entire I_OUTrange. Current control mode

provides fast transient response and improves

loop stabilization.

•

Full protection features include over-current

protection (OCP) and thermal shutdown.

•

The MPQ4418A offers a compact solution that

requires a minimal number of readily available,

standard, external components, and is available

in a small TSOT23-8 package.

•

Thermal Shutdown

Available in a TSOT23-8 Package

Available in AEC-Q100 Grade 1

APPLICATIONS
