It delivers one 3 A channel and two 2 A channels from a single 4.5 V to 18 V input rail, with all three outputs adjustable down to 0.6 V. The synchronous rectifier is integrated, so no external Schottky catch diode is needed.
What the 3 A / 2 A rating means for your BOM
The 3 A output is the primary rail — typically the core or I/O supply — while the two 2 A outputs handle auxiliary loads like PLL, memory, or peripheral buses. The 0.6 V minimum output lets it feed modern low-voltage cores without an extra LDO.
Cut Tape (CT) is also listed for prototype or small-batch orders.
Package and rework — the QFN reality
Reflow profile should follow the JEDEC standard for QFN; the exposed pad needs a good solder joint for both thermal and electrical connection to the ground plane.
