ME2135 Power Management IC – 300mA DC/DC Step-Up Charge Pump Converter | 1.8–5.5V, 650kHz | SOT23-6 DFN2×2-6L

The ME2135 is a compact Power Management IC integrating a DC/DC step-up charge pump converter with built-in NMOS and PMOS switches, designed for low-noise and inductor-free boost applications.
It operates from a 1.8V to 5.5V input voltage range and provides a regulated output voltage from 2.7V to 5.0V.

With a 650kHz switching frequency and ±3% output accuracy, the ME2135 delivers up to 300mA output current, making it well suited for light-load voltage boosting such as 3V to 3.3V conversion in compact portable electronics.
