  • MP2359 1.2A, 24V, 1.4MHz Step-Down Converter in a TSOT23-6

    The MP2359 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. The MP2359 requires a minimum number of readily available standard external
    components. The MP2359 is available in TSOT23-6 and SOT23-6 packages.
