MPQ2459

0.5A, 55V, 480KHz, Step-Down Converter

in a TSOT23-6 Package

AEC-Q100 Qualified

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MPQ2459 is a monolithic, step-down,

switch-mode converter with a built-in power

MOSFET. It achieves a 0.5A peak output

current over a wide input-supply range with

excellent load and line regulation. Current mode

operation provides a fast transient response

and eases loop stabilization. Fault protections

include cycle-by-cycle current limiting and thermal

shutdown.



Guaranteed Industrial/Automotive Temp

Range Limits.

0.5A Peak Output Current

1Ω Internal Power MOSFET

Stable with Low-ESR Ceramic Output

Capacitors

Up to 90% Efficiency

0.1μA Shutdown Mode

Fixed 480kHz Frequency

Thermal Shutdown

Cycle-by-Cycle Over-Current Protection

Wide 4.5V-to-55V Input Operating Range

Output Adjustable from 0.81V to 0.95×VIN

Available in a TSOT23-6 Package

Available in AEC-Q100 Grade 1



The MPQ2459 requires a minimal number of

readily-available, standard, external components.

The MPQ2459 is available in a TSOT23-6

package.

APPLICATIONS



Power Meters

Distributed Power Systems

Battery Chargers

Pre-Regulators for Linear Regulators

WLED Drivers
