ME2108 Power Management IC – 400mA DC/DC Step-Up Converter | 0.9–6.5V, 180kHz, SOT23-5 / SOT89-3 / TO92

The ME2108 is a low-power Power Management IC integrating a DC/DC step-up (boost) converter with a built-in NMOS power switch, optimized for low-cost and battery-powered designs.
It operates from a 0.9V to 6.5V input voltage range and supports an output voltage from 2.0V to 7.0V.

Using PFM operation at 180kHz, the ME2108 delivers up to 400mA output current with ±2.5% regulation accuracy, making it suitable for 3V to 5V boost applications.
