Rated for -40°C to 85°C ambient, the MAX1797EUA+ fits industrial control, outdoor telecom, automotive cabin, and portable instrumentation where the board sees temperature swings but not under-hood extremes. The synchronous rectifier helps maintain efficiency across load and temperature, reducing heat dissipation in a small package.","metaTitle":"MAX1797EUA+ Boost Regulator IC, 800 mA Switch","metaDescription":"Maxim MAX1797EUA+ step-up DC-DC converter with 800 mA switch, 500 kHz switching, adjustable output from 2 V to 5.5 V.

The synchronous rectifier helps reduce losses compared to a diode-based boost, but actual efficiency depends on input voltage, output load, and inductor selection."},{"question":"How do I adjust the output voltage with MAX1797EUA+?","answer":"The output is set by an external resistor divider connected to the feedback pin, or by selecting one of the preset voltages (3.3 V or 5 V) through the programmable output type.
