W705
W705 - Brand New IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
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 .
