Step-up boost converter in a SOT-23-6 — what it delivers
The MAX1834EUT+T is a step-up (boost) switching regulator with an adjustable output from 2 V to 5.5 V, from an input of 1.5 V to 5.5 V.
Input and output range — what it means for your rail
The input range spans 1.5 V to 5.5 V. The output is adjustable from 2 V to 5.5 V via external feedback resistors.
150 mA output — sizing the load budget
The 150 mA output current is the maximum the part can source. That limits the downstream load to small microcontrollers, op-amps, or a few LEDs.
Synchronous rectification — why it matters
The MAX1834EUT+T includes a synchronous rectifier on-chip. That replaces the usual Schottky diode with a low-Rds(on) FET, cutting forward drop and improving efficiency at light loads.
Lifecycle and sourcing
The MAX1834EUT+T is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect, so it can be specified into new designs without near-term obsolescence risk. For dual-sourcing, a pin-compatible alternative is the MAX1834EUT+T itself — no direct second source is listed in the record, but the part is widely stocked.
