DESCRIPTION
Demonstration circuit 1261A features the LTM
down μModule
4.5V to 36V input supply. As a step-down converter, the
LTM8022 requires a minimum amount of headroom to keep
the output in regulation. The device may be synchronized
to an external clock or allowed to enter low ripple Burst
Mode
appropriate signal to the SYNC pin. Current sharing with
another LTM8022 is enabled by tying the VIN, VOUT and
SHARE pins together to support higher output loads.
