The Analog Devices MAX1682EUK+T is a charge pump voltage doubler that delivers a fixed output of twice the input voltage (2Vin) from a single positive supply. The switching frequency is 12 kHz, and no synchronous rectifier is used.
The fixed 2Vin output doubles the input voltage. The 45 mA output current ceiling sets the load budget.
Both are charge pump voltage doublers in SOT-23-5. The MAX828 switches at 12 kHz and delivers 25 mA typical output; the MAX1682EUK+T also switches at 12 kHz but is rated for 45 mA output, giving it a higher load current capability for the same package and pinout.
The MAX828 is a pin-compatible charge pump doubler in the same SOT-23-5 footprint, but its output current is lower (25 mA typical). For a direct 45 mA replacement, the MAX1682EUK+T itself is the active part; no official second-source alternate is listed in the record.
