MP86957

Intelli-PhaseTM Solution (Integrated HS/LS-FETs and Driver) in 5mmx6mm LGA

Datasheet

Description

The MP86957 is a monolithic half-bridge with built-in internal power MOSFETs and gate drivers. It achieves 70A of continuous output current over a wide input supply range.

The MP86957 is a monolithic IC approach that can drive up to 70A per phase. Integration of drivers and MOSFETs results in high efficiency due to optimal dead time and parasitic inductance reduction. This small 5mmx6mm LGA device can operate from 100kHz to 3MHz.

The MP86957 offers many features to simplify system design. This device works through controllers with a tri-state PWM signal. It also comes with Accu-Sense^TM current sense to monitor the inductor current, and temperature sense to report junction temperature.

The MP86957 is ideal for server applications where efficiency and small size are at a premium.

Which intelliSense drivers can be driven at 5 MHz by MP2884A?

...e forum. I believe the highest fsw intelliphase on the website is also from that same teardown. The MP86957 can operate up to 3MHz.
