Boost converter for low-voltage rails
The MAX1674EUA+ is a step-up (boost) switching regulator from Analog Devices, designed to generate a higher output voltage from a low input source. It delivers up to 750 mA on the internal switch, making it suitable for powering small loads from a single-cell battery or a 3.3V rail that needs a 5V boost.
Package and board-fit
Supplied in tube packaging, it integrates easily into pick-and-place assembly for low-to-medium volume runs. Switching frequency is limited to 500 Hz, which means the external inductor and capacitor values will be larger than in a higher-frequency design, but switching losses stay low.
