    MP2462GJ-Z 4.2-32V, 2A, 800kHz Synchronous Step-Down Converter TSOT23

    The MPS MP2462GJ-Z is a Synchronous Step-Down Converter. It operates from a 4.2 V to 32 V input, is rated for 2 A and switches at 800 kHz. It is supplied in a TSOT23 package.

    The MP2462 is a synchronous, step-down, switching regulator with integrated, internal, high-side and low-side power MOSFETs (HS- FETs and LS-FETs, respectively).

    Applications

    • Battery-Powered Systems
    • Smart Homes
    • Wide Input Range Power Supplies

    Design Notes

    • Size the inductor for the ripple current at the actual switching frequency, typically 30% of the DC load — not for the DC rating alone.
    • The hot loop from input capacitor through the switch to ground sets conducted EMI. Keep that copper area as small as the layout allows.
    • Output ripple is set by the capacitor ESR and its DC-bias derating; a 10 µF ceramic often behaves like 4 µF at the rated output voltage.
    • Route the feedback divider from the output capacitor terminals, away from the switch node.
