DEMO MANUAL DC1414B-B
Demonstration circuit 1414B-B is easy to set up to evalu-
ate the performance of the LTM4601AHVEV. Please refer
to Figure 1 for proper measurement equipment setup and
follow the procedure below:
1. Place jumpers in the following positions for a typical

6. For Margining function test, place jumper MARG0 and
signal between IOSTEP CLK and GND pins. Pulse am-
plitude 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).
