ME2104 Power Management IC – 200mA DC/DC Step-Up Converter | 0.9–6V, up to 1.2MHz, SOT23-5

The ME2104 is a compact DC/DC step-up (boost) converter IC with built-in dual NMOS power switches, designed for ultra-low power applications.
It operates from a 0.9V to 6V input voltage range and provides an adjustable output voltage from 1.8V to 5.0V.

Featuring PFM control with a switching frequency ranging from 0kHz to 1.2MHz, the ME2104 delivers up to 200mA output current with ±2% output accuracy, ideal for 3V to 3.3V boost conversion.
