CM8501C Datasheet, PDF (5/6 Pages) List of Unclassifed Manufacturers – 1.5A BUS TERMINATOR

FUNCTIONAL DESCRIPTION
CM8501C
1.5A BUS TERMINATOR
The CM8501C is a switching regulator that is capable of
sinking and sourcing 1.5A of current without an external heat
sink.
The CM8501C integrates power MOSFETs that are capable
of source and sink 1.5A of current while maintaining excellent
voltage regulation. The output voltage can be regulated within
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.
OUPUTS
The output voltage pins (VL) are tied to the databus, address,
or clock lines via an external inductor. Output voltage is
determined by the VCCQ and is determined by the VCCQ.
INPUTS
The input voltage pins (VCCQ) determine the output voltages
(VL). At CM8501C, the output voltage is always 50% of the
VCCQ input. VCCQ is suggested to connect to VCCQ of
memory module for better tracking with memory VCCQ.
OTHER SUPPLY VOLTAGES
Several inputs are provided for the supply voltages: PVDD and
VCCA
The PVDD provide the power supply to the power MOSFETs.
VCCA provide the voltage supply to the logic section and
internal error amplifiers of CM8501C.
FEEDBACK
The VFB pin is an input that can be used for closed loop
compensation. This input is derived from the voltage output.
AGSEN pin is a contact node of internal resistor divider for
remote sense.
