ME3116
1A up to 40V Input Step-Down DC/DC Regulator ME3116
General Description
Features
The ME3116 is PWM DC/DC buck (step-down) regulators. With a wide input range from 4.75V-40V, they are suitable for a wide range of applications such as power conditioning from unregulated sources. They feature a low RDSON (0.9Ωtypical) internal switch for maximum efficiency 90%. Operating frequency is fixed at 550 KHz allowing the use of small external components while still being able to have low output voltage ripple. The system has PWM and PFM switching function to ensure high efficiency under low load. The built-in soft-start prevents inrush current at turn-on. the ME3116 is optimized for up to 1A load current. Both have a 0.8V nominal feedback voltage.
