Product Description

The mEZD81260A is a digital synchronous, step-down, COT control mode, open frame power module for high density DC/DC power application. It can provide 60A continuous output current. The mEZD81260A is targeted for applications such as telecom and networking systems. It adopts digital control algorithm and can achieve fast transient response. It can be configured as dual phase or dual rail operation. At the dual phase operation mode, the mEZD81260A has perfect interleaving and current sharing performance with proprietary digital technology used. At the dual rail operation mode, the mEZD81260A can achieve programmable power on/off sequence. The mEZD81260A need least external discrete components for sense and control circuit. Almost all operation parameters and configuration parameters can be easily defined through PMBus commands with MPS digital programmable GUI. The mEZD81260A provides full programmable fault protection features including: UVLO, UVP, OVP, OCP and OTP.
