MPQ4419

1A, 36V, High-Efficiency, Synchronous

Step-Down Converter, AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ4419 is a high-efficiency, synchronous,

rectified, step-down, switch-mode converter

with built-in power MOSFETs. It offers a very

compact solution that achieves 1A of

continuous output current, with excellent load

and line regulation across a wide input supply

range.



Wide 4V to 36V Continuous Operating Input

Range

90mΩ/55mΩ Low R_DS(ON)Internal Power

MOSFETs

High-Efficiency Synchronous Mode

Default 410kHz Switching Frequency

Synchronizes to a 200kHz to 2.2MHz

External Clock

High Duty Cycle for Automotive Cold Crank

Conditions



The MPQ4419 uses synchronous mode

operation to achieve higher efficiency over the

output current load range. Current-mode

operation provides fast transient response and

eases loop stabilization.



Forced Continuous Conduction Mode

(FCCM)



Internal Soft Start

Power Good

Full protection features include over-current

protection (OCP) and thermal shutdown.

Over-Current Protection (OCP), Hiccup

Mode, and Thermal Shutdown

Output Adjustable from 0.8V

Available in a TSOT23-8 Package

Available in AEC-Q100 Grade 1

The MPQ4419 requires a minimal number of

readily available, standard external components,

and is available in a compact TSOT23-8

package.
