Product Descriptions
The MP2357 is a monolithic step-down switch mode converter with a built-in internal 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 fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown.
The MP2357 requires a minimum number of readily available standard external components. The MP2357 is available in TSOT23-6 and SOT23-6 packages.
