CM8562B
1.8A SINK & SOURCE ADJUSTABLE LINEAR REGULATOR
FUNCTIONAL DESCRIPTION
The CM8562B is a linear regulator that is capable of sinking INPUTS
and sourcing 1.8A of current without an external heat sink.
The input voltage pins (VIN) determine the output voltages
(VOUT). At CM8562B, the desired output voltage could be
The CM8562B integrates power MOSFETs that are capable programmable by two external voltage divider resistors. VIN is
of source and sink 1.8A of current while maintaining excellent suggested to connect to VDDQ of memory module for better
voltage regulation. The output voltage can be regulated within tracking with memory VDDQ.
3% or less by using the external feedback. Separate voltage
supply inputs have been added to fit applications with various
power supplies for the databus and power buses.
OTHER SUPPLY VOLTAGES
VCCA provide the voltage supply to the logic section and
OUTPUTS
internal error amplifiers of CM8562B.
The output voltage pins (VOUT) are tied to the databus,
address, or clock lines via an external inductor. Output voltage
is determined by the VIN.
