ME3110 Power Management IC – 2A Synchronous DC/DC Buck Converter | 4.4–18V, 500kHz, SOT23-6

The ME3110 is a wide-input Power Management IC featuring a synchronous DC/DC step-down (buck) converter suitable for higher-voltage portable and industrial applications.
It supports a 4.4V to 18V input voltage range and provides an adjustable output voltage from 1.2V to 7V using a 0.6V feedback reference.

With automatic PFM/PWM operation, the ME3110 delivers up to 2A output current while maintaining stable regulation and high efficiency.
Its 500kHz switching frequency provides a balance between efficiency and EMI performance.
