AMS222 used as Clock Signal to Synchronize two Switching Regulators
PRODUCT DESCRIPTION
AMS222 is a silicon clock generator with complementary output, programmable frequency using a single resistor from 10KHz to
6MHz.
The Output B is 180o phase from Output A, and the signals do not overlap does allow to drive critical circuits where break-before-
make is very important. It operates from as low as 2.7V to high 15V consuming just 1.2mA of power. The output drive is capable
to drive capacitive loads up to 50pF and resistive loads up to 3mA. The high stability of the output frequency and it’s immunity to
supply variation is due to internal temperature compensated voltage reference. Having a good power supply rejection ratio, the
device works very well in electrically noisy environments. The only critical element is the Fset resistor that should be placed as
close as possible to the package to avoid parasitic capacitance and PCB traces cross-talk.
