APW7055BNC-TR規(guī)格書(shū)詳情

General Description

The APW7055 provides the power control and protections for two output voltages on M/B DDR applications. It integrates one PWM controller , one source-sink linear controller(LC) for DDR source-sink purpose, as well as the monitor and protection functions into a single package. The PWM controller supplies the VMEM(2.5V) with a standard buck converter. The source-sink linear controller regulates VTT(1.25V) power for DDR Termination.

Additional built-in over-voltage protection (OVP) will be started when the VMEM output is above 115 of the internal DAC setting(VDAC) . OVP function will shut down the upper MOSFET and disable all output voltage . The PWM controller’s over-current function monitors the output current by sensing the voltage drop across the upper MOSFET‘s rDS(ON) , eliminating the need for a current sensing resistor .
