Hot-selling and scarce MP2259DT-LF-Z 1A 16V 1.4MHz Step-Down Converter SOT23

Product Descriptions

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.

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.
