ME3148 Power Management IC – 3A Asynchronous DC/DC Buck Converter | 8–36V, 160kHz, ESOP8

The ME3148 is a high-current asynchronous DC/DC step-down (buck) converter designed for wide-input, high-power applications.
It supports an 8.0V to 36V input voltage range and provides an adjustable output voltage from 1.25V to 33V using a 1.25V feedback reference.

With up to 3A output current, the ME3148 operates in PWM mode and achieves stable regulation with ±1.5% output accuracy.
Its 160kHz switching frequency optimizes efficiency and thermal performance for higher-power designs.
