MP2420

75V, 0.3A Synchronous

Step-Down Converter with Watchdog

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2420 is a step-down switching regulator

with integrated high- and low-side, high-voltage

power MOSFETs. It achieves a highly efficient

output of up to 0.3A, and 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

•

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.

•

Integrated Window Watchdog

Power-On Reset during Power Up and

Under-Voltage Lockout (UVLO)

Programmable Short Window Mode or Long

Window Mode

Low Shutdown Mode Current of 5μA

Available in a TSSOP-16 EP Package

•

The MP2420 allows for high-power conversion

efficiency over a wide load range by scaling

down the switching frequency under light-load

conditions to reduce switching and gate driver

losses. The start-up switching frequency and

short circuit can also be scaled down to prevent

an inductor current runaway.

•

APPLICATIONS

•

Automotive Systems

Industrial Power Systems

Distributed Power Systems

Battery-Powered Systems

Full protection features include under-voltage

lockout (UVLO) and thermal shutdown. Thermal

shutdown provides reliable, fault-tolerant

operation.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
