The MP8500A is a dual-channel, high-current, intelligent synchronous rectifier (SR) with an integrated low on resistance (R_DS(ON)) MOSFET that is optimized for LLC and full-bridge converters. With its built-in, low-R_DS(ON) MOSFET, the device can deliver up to 40A of continuous output current (I_OUT) per IC at room temperature. With airflow, the continuous I_OUT can reach 50A.

The MP8500A offers many features to simplify system design. It works with MPS's LLC controllers, and comes with Accu-Sense^TM current sense to monitor the current going through the SR. It also offers temperature sense to report the junction temperature (T_J).

The device supports working in MOSFET-only mode or SR mode. It also supports partial operation skipping if multiple MP8500As are in a parallel circuit, which makes the application more flexible. The highly integrated MOSFET and gate driver offer fast turn-on and turn-off times to enable high power density and high efficiency.

The MP8500A requires a minimal number of external components, and is available in an LGA-39L (5mmx5mm) package.
