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 tri-

state 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.
