Linear Technology DC1780A-C Demo Manual page 3

QUICK START PROCEDURE
6. (Optional) LTM4620 can be synchronized to an external
clock signal. Place the JP1 jumper on EXT_CLK and
apply a clock signal (0V to 5V, square wave) on the
EXT_CLK test point.
7. (Optional) The outputs of LTM4620 can track another
supply. The output voltage tracks the voltage on
TRACK_CONTROL when a valid signal is applied on
the test point.
* Note: The output current is measured with a mV-voltage meter across a 1% accurate shunt resistor.

8. (Optional) DC1780A-C can be configured to a dual
outputs configuration with V
and V
R61 and 0.1μF on C14. Remove R22, R23, R24, R26,
R27, R28, R32, R33, R35. Output voltage V
by R37 based on the equation V
R37).
