MPQ2420-AEC1

75V, 0.3A, Synchronous

Step-Down Converter with Watchdog

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ2420 is a step-down switching

regulator with integrated high- and low-side,

high-voltage power MOSFETs. It provides a

highly efficient output of up to 0.3A. The

integrated watchdog adds additional security

redundancy to the system.



20μA Quiescent Current for Buck Only

Wide 4.5V to 75V Operating Input Range

(80V ABS MAX)

1.2Ω/0.45Ω Internal Power MOSFETs

Programmable Soft Start

FB Tolerance: 1% at Room Temperature,

2% at Full Temperature

Adjustable Output Voltage

Integrated Window Watchdog

Power-On Reset during Power-Up

Under-Voltage Lockout and Thermal

Shutdown

Programmable Short Window Mode or Long

Window Mode

Low Shutdown Mode Current of 5μA

TSSOP-16 EP Package

Available in AEC-Q100 Grade 1



The wide 4.5V to 75V input range accommodates

a variety of step-down applications in an

automotive environment. A 5μA shutdown

mode quiescent current in a full temperature

range is ideal for battery-powered applications.

It allows for high-power conversion efficiency

over a wide load range by scaling down the

switching frequency under a light-load condition

to reduce switching and gate driver losses. The

start-up switching frequency and short circuit

can also be scaled down to prevent inductor

current runaway.



APPLICATIONS

Full protection features include under-voltage

lockout (UVLO) and thermal shutdown. Thermal

shutdown provides reliable, fault-tolerant

operation.
