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-SenseTM 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.
