DESCRIPTION

The MP87190 is a monolithic half-bridge with built-in internal power MOSFETs and gate drivers. It achieves up to 90A of continuous output current (IOUT) across a wide input voltage (VIN) supply range.

Quiet SwitcherTM technology (QST) utilizes a proprietary circuit design that can only be achieved in a monolithic architecture to suppress voltage ringing. This technology limits the peak switching voltage to <2V above VIN, improving device reliability, lowering EMI, and reducing sensitivity to PCB layout.

The MP87190 offers many features to simplify system design. This device operates with tristate pulse-width modulation (PWM) signal controllers, and features Accu-SenseTM current sensing and temperature sensing, to monitor the inductor current (IL) and report the junction temperature (TJ), respectively.

The MP87190 is ideal for server and telecom applications where efficiency and small size are at a premium. The MP87190 is available in TLGA-41 (5mmx6mm) package.
