The boost channel delivers 800 mA at an adjustable output from 2.5 V to 5.5 V; the LDO provides 500 mA at either 2.85 V or an adjustable voltage. Switching at 1 MHz keeps the external inductor and capacitors small, which matters when board area is tight — think battery-powered handhelds, portable instruments, or any design that needs a main rail plus a clean auxiliary rail from a single Li+ cell or two alkaline cells.
Output 1 (boost) is adjustable from 2.5 V to 5.5 V at 800 mA. Output 2 (LDO) is 2.85 V or adjustable at 500 mA.
