ME2129 Power Management IC – 500mA DC/DC Step-Up Converter | 0.9–6V, 300kHz, SOT23-5

The ME2129 is a flexible DC/DC boost converter IC featuring a built-in NMOS power switch, designed for adjustable high-voltage boost applications.
It operates from a 0.9V to 6V input voltage range and supports an output voltage up to 20V using a 1.25V feedback reference.

Using PFM/PWM control at 300kHz, the ME2129 delivers up to 500mA output current with ±2% output accuracy, making it ideal for 3V to 5V boost designs.
