Product details

Dual-output power in a single 16-TSSOP

The MAX1765EUE+ from Maxim Integrated packs a synchronous step-up (boost) regulator and a linear (LDO) regulator into one 16-TSSOP package with an exposed pad for thermal relief. 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.

Lifecycle and sourcing reality

No second-source or pin-compatible alternate is listed in the official record, so dual-sourcing would require a board redesign if a second source is needed.

Frequently asked questions

What are the output voltages of MAX1765EUE+?

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.
