ME2101 Power Management IC – 350mA DC/DC Step-Up Converter | 0.9–6.5V, 100kHz, SOT23-5 / SOT23-3 / SOT89-3

The ME2101 is a compact Power Management IC designed as a DC/DC step-up (boost) converter with a built-in NMOS power switch.
It supports a 0.9V to 6.5V input voltage range and provides an output voltage from 2.0V to 5.0V, suitable for low-power boost designs.

Operating in PWM mode at 100kHz, the ME2101 delivers up to 350mA output current with ±2.5% output accuracy, ideal for 3V to 3.3V conversion in cost-sensitive applications.
