ME3116AM6G

The ME3116AM6G is Microne's (Nanjing Microne Electronics) ordering code for the ME3116, a 40 V input, 1 A PWM asynchronous buck converter in SOT-23-6; Microne's official selection manual lists the ME3116 line verbatim as a 40 V input, 1 A PWM asynchronous step-down converter, and the AM6G suffix is Microne's own ordering form for this package. The 40 V ceiling lets one design serve 12 V and 24 V industrial and vehicle-accessory rails with margin for load-dump and hot-plug transients, while the 1 A output class covers logic, sensor and interface rails without the cost of a multi-amp controller. As an asynchronous design it rectifies through an external catch diode rather than a second MOSFET: the bill of materials gains one diode, but there is no shoot-through risk and no bootstrap or dead-time tuning, which keeps small power stages simple and predictable. Selection advice: choose the freewheel diode for the full 40 V input plus ringing - a 60 V-class Schottky is the conservative pick - keep the input capacitor and diode loop tight against the SOT-23-6, and quote the complete ME3116AM6G code, since Microne's ME31xx family spans many input ratings and current classes under similar numbers.
