MP2492

2A, 55V, 100kHz Step-Down Converter

with Programmable Output Current Limit

The Future of Analog IC Technology

DESCRIPTION

FEATURES

•

Wide 4.5V to 55V Operating Input Range

Programmable up to 2A Output Current

Output Adjustable from 0.8V to 15V

Programmable Output Current Limit without

power loss

The MP2492 is a monolithic step-down switch

mode converter with a programmable output

current limit. It achieves 2A 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

Fixed 100kHz Frequency

Low EMI signature

Thermal Shutdown

Cycle-by-Cycle Over Current Protection

Available in QFN10 and SOIC8E Packages

The maximum output current can be

programmed by sensing current through the

inductor DC resistance (DCR) or an accurate

sense resistor.

•

MP2492 achieves low EMI signature with well

controlled switching edges.

Fault condition protection includes cycle-by-cycle

current limiting, and thermal shutdown.

APPLICATIONS

The MP2492 requires a minimum number of

readily available standard external components.

The MP2492 is available in QFN10 (3mm x 3mm)

and SOIC8E packages.
