MP2259

1A, 16V, 1.4MHz

Step-Down Converter

The Future of Analog IC Technology

FEATURES

DESCRIPTION

•

1A Output Current

The MP2259 is a monolithic integrated step-

down switch mode converter with an internal

power MOSFET. It achieves 1A continuous

output current over a wide input supply range

with excellent load and line regulation.

0.5Ω Internal Power MOSFET Switch

Stable with Low ESR Output Ceramic

Capacitors

•

Up to 92% Efficiency

0.1μA Shutdown Mode

Fixed 1.4MHz Frequency

Thermal Shutdown

Cycle-by-Cycle Over Current Protection

Wide 4.5V to 16V Operating Input Range

Output Adjustable from 0.81V to 14V

Available in TSOT23-6 and SOT23-6 Packages

Current mode operation provides fast transient

response and eases loop stabilization.

Fault condition protection includes cycle-by-cycle

current limiting and thermal shutdown.

The MP2259 requires a minimum number of

readily available standard external components.

The MP2259 is available in TSOT23-6 and

SOT23-6 packages.
