MP4583GQVE-Z 4.5-100V, 3A, 400kHz Synchronous Step-Down DC/DC Converter QFN-19
The MPS MP4583GQVE-Z is a Synchronous Step-Down DC/DC Converter. It operates from a 4.5 V to 100 V input, is rated for 3 A and switches at 400 kHz. It is supplied in a QFN-19 package.
The MP4583 is an 8μA quiescent current (IQ), synchronous step-down converter with integrated high-side and low-side MOSFETs (HS-FET and LS-FET, 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.
