DEMO MANUAL DC1590B LTC3880: Dual Output Step-Down DC/DC Controller with Digital Power Management DESCRIPTION Demonstration circuit 1590B is a dual output synchronous buck converter featuring the LTC®3880EUJ, a dual output peak current mode controller with digital power system management. There are two versions of the board available: • DC1590B-A: Senses the output current across a sense resistor and has a default switching frequency of 350kHz. • DC1590B-B: Senses output current with the inductor DCR and has a default switching frequency of 425kHz. Either version can be populated with the LTC3880EUJ-1, instead of the LTC3880EUJ, which allows the user to provide bias power to the IC from an external power supply. These boards provide two programmable outputs of 20A each. The factory default settings are 1.8V for each output. Both boards power up to default settings and produce power based on configuration resistors without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter.

Refer to Figure 3 for proper measurement equipment setup and follow the procedure below: Note: When measuring the input or output voltage ripple, care must be taken to avoid a long ground lead on the oscilloscope probe. Measure the output voltage ripple by touching the probe tip directly across the C32 or C34. See Figure 5 for proper scope probe technique. 1. Make sure jumpers are in the following positions: JUMPER POSITION FUNCTION JP1 OFF Write Protection of LTC3880 JP2 NC RUN0 to RUN1 JP3 ON 3.3V Test—3.3V for LED indicator JP4 OFF EXTVCC_DRV—External VCC for LTC3880-1 JP5 NC GPIO0B to GPIO1B—Tie GPIOs Together 2. With power off, connect the input power supply to VIN and GND. Connect active loads to outputs. 3. Make sure both RUN switches are off. 4. Turn on the power at the input. 5. Turn on RUN switches as desired. 6. Check for the correct output voltages. VOUT1 = VOUT2 = 1.8V ± 0.5% Note: If there is no output, temporarily disconnect the load to make sure that the load current is not set too high. 7. Once the proper output voltages are established, adjust the loads within the operating range and observe the output voltage regulation, ripple voltage, efficiency and other parameters. 8. Connect the dongle and control the output voltages from the GUI. See “LTpowerPlay GUI for the LTC3880 Quick Start Guide” for details. Connecting a PC to DC1590B You can use a PC to reconfigure the power management features of the LTC3880 such as: nominal VOUT, margin set points, OV/UV limits, temperature fault limits, sequencing parameters, the fault log, fault responses, GPIOs and other functionality. The DC1613A dongle may be plugged in regardless of whether or not VIN is present. Note: Make sure that the input voltage does not exceed 24V. dc1590bf 2 DEMO MANUAL DC1590B QUICK START PROCEDURE Figure 1. Demo Setup with PC Plug the dongle into the correct connector. Dongle can be hot plugged. Figure 2. Dongle Connector Locations dc1590bf 3 DEMO MANUAL DC1590B QUICK START PROCEDURE High Output Current Configuration By default, the DC1590B powers up with two independently adjustable outputs at 1.8V each. For >20A operation, it is recommended to install the optional MOSFETs Q9 and Q10 for large step-down ratios and Q7 and Q8 for small step-down ratios. Combining DC1590B with Other Digital Power Demo Boards The DC1590B may be plugged together in a multi-board array with other digital power boards using optional J7 and J8. Figure 3. Dual Output Test Setup dc1590bf 4 DEMO MANUAL DC1590B QUICK START PROCEDURE Measuring Efficiency (See Figure 4) To accurately measure efficiency of any configuration, do the following: • Set JP3 to OFF to disable the regulator that provides power to various auxiliary demo board components like LEDs. • Measure VIN across the input ceramic capacitor (C18, C19). Measure VOUT across the output ceramic capacitor (C24, C25). To use the onboard LDO to drive INTVCC, make the following modifications to the demo board: • Set JP4 to ON so that U7 provides the drive to EXTVCC. U7 takes the place of the external power supply. • Install R60. To accurately measure efficiency of a demo board containing an LTC3880-1, • Drive INTVCC from an external source through the pin named: INTVCC/EXTVCC. Evaluating the LTC3880-1 • Set JP4 to OFF to disable U7. For applications that require the highest possible efficiency, the LTC3880-1 allows the user to supply the bias voltage and gate driver current from an external power supply. Connect the power supply, 4.8V to 5.2V, to the EXTVCC pin. Obtain a DC1590B with an LTC3880-1 installed from your Linear Technology Field Applications Engineer. • Measure VIN across the input ceramic capacitor (C18, C19). Measure VOUT across the output ceramic capacitor (C24, C25).
