ME3125 Power Management IC – 5A Synchronous DC/DC Buck Converter | 4.6–24V, 500kHz, ESOP8

The ME3125 is a wide-input Power Management IC featuring a synchronous DC/DC step-down (buck) converter, designed for high-current and wide-voltage applications.
It supports a 4.6V to 24V input voltage range and provides an adjustable output voltage from 0.6V to 5V using a 0.6V feedback reference.

Capable of delivering up to 5A output current, the ME3125 operates in automatic PFM/PWM mode with high efficiency and stable regulation.
Its 500kHz switching frequency makes it suitable for compact yet powerful DC/DC designs.
