ME3116 Power Management IC – 1A Asynchronous DC/DC Buck Converter | 4.75–40V, 550kHz, SOT23-6

Shanghai Belling

The ME3116 is a high-voltage Power Management IC integrating an asynchronous DC/DC step-down (buck) converter, suitable for industrial and embedded applications requiring higher output current.
It supports a 4.75V to 40V input voltage range and offers an adjustable output voltage from 1.2V to 5V using a 0.8V feedback reference.

Delivering up to 1A output current, the ME3116 operates in PWM mode with stable regulation and ±1.5% output accuracy.
Its 550kHz switching frequency ensures reliable operation and efficient power conversion.
