QUICK START PROCEDURE

Demonstration circuit 1414 is easy to set up to evaluate the

performance of the LTM4601AEV. 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

1.5V

1.5V

2. With the power off, connect the input power supply,

load and meters as shown in Figure 1. Preset the load

to 0A and V

supply between 5V to 20V.

3. Turn on the power at the input. The output voltage

should be 1.5V ± 1%.

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. Output ripple should be measured at

J4 with a BNC cable.

5. (Optional) To review load transient performance, apply

an adjustable 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).

6. (Optional) To implement output voltage margining,

place jumpers MARG0 and MARG1 in the configuration

shown according to the table below. The output voltage

measured at J4 will respond accordingly.
