Demonstration circuit DC2081A-B is easy to set up to
evaluate the performance of the LTM4630-1. Please refer
to Figure 1 for proper measurement setup and follow the
procedure below:
1. 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 to 12V.
2. Turn on the power supply at the input. The output volt-
age should be 1.0V ± 0.8% (0.992V ~ 1.008V).
Quick start proceDure
3. Once the proper output voltage is established, adjust the
load within the operating range and observe the output
voltage regulation, output voltage ripple, efficiency and
other parameters. Output ripple can be measured at J6
with BNC cables.
4. (Optional) For optional load transient test, apply an ad-
justable pulse signal between “IOSTEP CLK” and “GND”
test point. Pulse amplitude (3V ~ 3.5V) sets the load
step current amplitude. The output transient current can
be monitored at the BNC connector J5 (15mV/A). The
pulse signal should have very small duty cycle (< 10%)
to limit the thermal stress on the transient load circuit.
