DEMO MANUAL DC1041A-A
Demonstration circuit DC1041A-A is an easy way to evalu-
ate the performance of the LTM4601EV. Please refer to
Figure 1 for proper measurement equipment setup and
follow the procedure below:
1. With the power supply off, connect the input power

output voltage regulation, ripple voltage, efficiency and
other parameters. Output ripple should be measured at
J4 with a BNC cable.

6. For Margining function test, place jumper MARG0 and
pulse signal between IOSTEP (E3) and GND pins.
Pulse amplitude sets the current step. The pulse signal
should have very small duty cycle (<15%) to limit the
thermal stress on the transient load circuit. The output
transient current can be monitored at BNC connector
J3 (10mV/A).
