ME2167 Power Management IC – 2.5A DC/DC Step-Up Converter | 2.7–12V, 200kHz–2MHz, DFN4.5×3.5 / QFN2.5×3.5

The ME2167 is a high-performance Power Management IC implementing a DC/DC step-up (boost) converter with built-in dual NMOS power switches, optimized for wide-input and high-current applications.
It supports a 2.7V to 12V input voltage range and provides an adjustable output voltage below 12.6V using a 1.2V feedback reference.

Operating over a wide switching frequency range from 200kHz to 2MHz, the ME2167 delivers up to 2.5A output current with ±2% output accuracy, making it suitable for 3.3V to 9V boost conversion in industrial and embedded systems.
