2 / 8 page 2 dc2367af DEMO MANUAL DC2367A QUICK START PROCEDURE Demonstration circuit DC2367A is an easy way to evaluate the performance of the LTM4632. Please refer to Figure 1 for test setup connections and follow the procedure below. 1. With power off, place the jumpers in the following positions for a typical application for 2.5VOUT1 and 1.25VOUT2 rails: JP1 JP2 JP3 JP4 JP6 RUN1 RUN2 TRACK/SS MODE VDDQ SEL ON ON SS CCM 2.5V 2. Before powering up the input supply and loads, preset the input voltage supply to be between 3.6V to 15V. Preset the load current for each output rail to 0A. 3. With power off, connect the loads, input voltage supply and meters as shown in Figure 1. 4. Turn on the input power supply. The output voltage me- tersforeachoutputrailshoulddisplaytheprogrammed output voltage ±1.5%. 5. Once the proper output voltages are established, ad- just the load current on each rail within the 0A to 3A range and observe each output rail’s load regulation, efficiency, and other parameters. 6. To observe increased light load efficiency place the mode pin jumper (JP4) in the BURST MODE position.
