MPQ2490

Industrial Grade, 1.5A, 36V, 700kHz

Step-Down Converter

with Programmable Output Current Limit

FEATURES

DESCRIPTION



Wide 4.5V to 36V Operating Input Range

Programmable up to 1.5A Output Current

Output Adjustable from 0.8V to 15V

Programmable Output Current Limit without

power loss

The MPQ2490 is a monolithic step-down switch

mode converter with programmable output

current limit. It achieves 1.5A continuous output

current over a wide input supply range with

excellent load and line regulation.



0.25Ω Internal Power MOSFET Switch

Stable with Low ESR Output Ceramic

Capacitors

The maximum output current can be

programmed by sensing current through the

inductor DC resistance (DCR) or an accurate

sense resistor.



95% Efficiency @ 500mA (Vo=5V)

Fixed 700kHz Frequency

Thermal Shutdown

Cycle-by-Cycle Over Current Protection

Available in QFN10 Package

Fault

condition

protection

includes

cycle•by•cycle current limiting and thermal

shutdown.

The MPQ2490 requires a minimum number of

readily available standard external components.

The MPQ2490 is available in QFN (3x3mm)

package.

APPLICATIONS



Industrial and Car Power Supplies

USB Power Supplies

Automotive Cigarette Lighter Adapters

Power Supply for Battery Chargers
