Description
The W705 model is an electronic component that belongs to the IC chips product category. It provides power control and protections for two output voltages on M/B DDR applications, integrating one PWM controller, one source-sink linear controller (LC) for DDR source-sink purpose and the monitor and protections functions into a single package. Besides, the W705 model has additional built-in over-voltage protection (OVP), which will shut down the upper MOSFET and disable all output voltage when the VMEM output is above 115% of the internal DAC setting (VDAC).
