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).

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.
