The MAX1724EZK50+T is a step-up (boost) DC-DC converter from Analog Devices, delivering a fixed 5V output from input rails as low as 0.8V and up to 5.5V. The internal switch is rated for 400mA, and the synchronous rectifier keeps conduction losses low in portable or battery-powered designs.
Input range and startup behaviour
Minimum input of 0.8V means the converter can start from a single alkaline cell or a Li-ion battery near its end-of-discharge voltage. The 5.5V maximum input covers two-cell alkaline or single-cell Li-ion without needing an external clamp.
Housed in a SOT-23-5 Thin / TSOT-23-5 package, the MAX1724EZK50+T occupies minimal board area. The supplier device package is TSOT-23-5, a common footprint for low-power DC-DC converters.
Temperature grade and environment
The RoHS3 compliance covers current EU and many global substance restrictions.
