DESCRIPTION
And RDSON of high side and low side switches are 170mΩ and 410mΩ respectively. In light load condition, ME3121 works in the PFM mode which has good efficiency performance. At this time, it has a constant switching frequency of 1 MHZ. ME3121 incorporates OTP, input UVLO, cycle by cycle current limit protection and output short circuit protection to improve reliability.APPLICATIONS
