Microne ME3123
ME3123 is a sync BUCK DC-DC converter IC, which integrates two NMOSFET power switches with low on-resistance. This product is capable of delivering 3A load current. When load current goes heavy, ME3123 works in a quasi PWM mode.DESCRIPTION
And RDSON of high side and low side switches are 110mΩ and 45mΩ respectively. In light load condition, ME3123 works in the PFM mode which has good efficiency performance. At this time, it has a constant switching frequency of 500kHZ. ME3123 incorporates OTP, input UVLO, cycle by cycle current limit protection and output short circuit protection to improve reliability.APPLICATIONS
