The MP5048A is a monolithic, integrated controller and switch. It contains a power MOSFET and circuitry that enable it to operate as a standalone device, or to be controlled by a hot-swap controller. The MP5048A is capable of driving up to 4A of continuous output current (IOUT) per device.
The MP5048A limits the inrush current to the load when a circuit card is inserted into a live backplane power source. This limits the backplane’s voltage drop. The MP5048A also limits the internal MOSFET current by controlling the gate voltage (VGATE) via the current-limit reference input.
The MP5048A offers many features to simplify system design. Its integrated solution monitors IOUT and the die temperature, which eliminates the need for an external current-sense resistor, power MOSFET, or thermal sensing. The MP5048A detects the power MOSFET gate, source, and drain short conditions to provide feedback for the controller. The device can be paralleled for higher current applications.
The MP5048A is available in a QFN-30 (5mmx5mm) package.

THE POWER OF DUAL-PHASE DRMOS TECHNOLOGY IN AI SYSTEMSARTICLEAs AI systems continue to push boundaries, current demands are rapidly increasing. Next-generation AI systems face a critical layout bottleneck caused by escalating current demands that now frequently reach the 1000A to 2000A threshold per socket. To supply this immense demand for low-voltage power stably while minimizing ripple, voltage regulator module (VRM) architectures are forced to aggressi...
