ME3111 Power Management IC – 3A Synchronous DC/DC Buck Converter | 4.8–18V, 500kHz, TSOT23-6

The ME3111 is a high-current Power Management IC integrating a synchronous DC/DC step-down (buck) converter for wide-input voltage applications.
It supports a 4.8V to 18V input voltage range and offers an adjustable output voltage from 1.2V to 7V using a 0.6V feedback reference.

Designed for improved regulation accuracy, the ME3111 delivers up to 3A output current with ±1.5% output accuracy.
Its 500kHz switching frequency ensures reliable performance in space-constrained power designs.
