Microne ME3108
ME3108 is a high efficiency, easy-to-use, COT synchronous step-down DC/DC converter with an input voltage range of 2.8V to 5.5V. The Voltage Mode Constant On-Time (COT) operation with internal compensation allows the transient response to be optimized over a wide range of loads and output capacitors. The main differences are: PWM / PFM automatic switching mode series; independent selection of working mode.DESCRIPTION
And its output voltage is fixed inside while delivering up to 2A of output current. Different chips have different working modes. In the automatic switching mode, the continuous mode works at a constant frequency of 1.2MHz, and it works in the discontinuous mode at light load, thereby achieving high efficiency characteristics in the full load range. ME3108 integrated a few protect circuits to make the system works in safety stations. It contains input Under-Voltage Lockout, over-current protection and short-circuit protection and over temperature protection. Feature● Output current:2A(TYP),2.5A(MAX)
