Product details

600 kHz synchronous buck in a 16-pin SSOP

The MAX1685EEE+ is a 1 A step-down (buck) switching regulator from Analog Devices, switching at 600 kHz with an integrated synchronous rectifier. The output is adjustable from 1.25 V up to the input voltage, with a fixed 3.3 V option available via the same die. The 16-pin SSOP (3.90 mm width) and the equivalent 16-QSOP supplier package fit compact layouts where height is constrained.

Active production, ROHS3, and sourcing posture

Sourced through independent distribution channels.

Frequently asked questions

Where can I buy MAX1685EEE+ and get a price?

Submit an RFQ for current availability and pricing against your BOM quantity.

What is the function and topology of MAX1685EEE+?

Step-down (buck) topology with a single positive output. The synchronous rectifier is integrated, so no external catch diode is needed.

What compliance documentation does Analog Devices provide for MAX1685EEE+?

ROHS3 compliant per the manufacturer's listing.
