IT2359 - 1.2A, 24V, 1.4MHz Step-Down DC-DC Converter


IT2359 is a monolithic step-down switch mode converter with a built-in power MOSFET. It achieves 1.2A 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.

IT2359 requires a minimum number of readily available standard external components and is available in SOT23-6 packages.
