6 A adjustable buck in a 6x6 TQFN
The MAX15303AA00+CM: Switching frequency is programmable from 300 kHz to 1 MHz via an external resistor, letting the designer trade inductor size against efficiency — a 1 MHz setting shrinks the magnetics for a compact point-of-load footprint.
Active production, ROHS3, no second source
No pin-compatible second source or official successor is published; the part is single-sourced from ADI.
Synchronous rectification and single-output adjust
Internal synchronous rectifier MOSFETs eliminate the external Schottky catch diode, keeping the BOM count low and the efficiency curve competitive into light loads. The single adjustable output is positive-configuration only. Shipped in tube packaging — not tape-and-reel — so the pick-and-place feeder setup expects a tube handler or a manual tray load for the 40-TQFN package.
