ME3113 Power Management IC – 3A Synchronous DC/DC Buck Converter | 4.5–18V, 500kHz, SOT23-6

The ME3113 is a wide-input Power Management IC featuring a synchronous DC/DC step-down (buck) converter, optimized for reliable mid-power applications.
It supports a 4.5V to 18V input voltage range and offers an adjustable output voltage from 0.6V to 5V using a 0.6V feedback reference.

With automatic PFM/PWM operation, the ME3113 delivers up to 3A output current while maintaining low quiescent current of 120µA.
Its 500kHz switching frequency ensures stable operation and reduced EMI in compact designs.
