DEMO MANUAL DC1392A
QUICK START PROCEDURE
Demonstration circuit 1392A is an easy way to evaluate the
performance of the LTM4604AEV. 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
1.2V OUT application:
4. Once the proper output voltage is established, adjust
the load within the operating range and observe the
output voltage regulation, ripple voltage, efficiency and
other parameters
5. To measure input and output ripple, please refer to
Figure 2 for proper setup.

6. For optional load transient test, apply adjustable pulse
signal between IOSTEP CLK and GND pins. Pulse am-
2. With power off, connect the input power supply, load
and meters as shown in Figure 1. Preset the load to
0A and V IN supply within the operating range of the
LTM4604A.
3. Turn on the power at the input. The output voltage
plitude sets the current step. The pulse signal should
have very small duty cycle (<5%) to limit the thermal
stress on the transient load circuit. The output tran-
sient current can be monitored at BNC connector J1
(10mV/A), the output voltage can be monitored at BNC
connector J2.
should be 1.2V ±2%.
