DEMO MANUAL DC2283A LTC3884EUK Polyphase Single 160A Output Synchronous Buck Converter with Power System Management Description Demonstration circuit 2283A is a high efficiency, high density, single-output Buck converter with 7V to 14V input range. The output voltage is adjustable from 0.5V to 1.5V, and can supply up to 160A of load current with a 1V output. The demo board offers the option to be configured as a dual-output converter, contact factory for details. VOUT0 can supply a 40A maximum load current and VOUT1 can supply a 120A maximum load current. The demo board features the LTC3884, a dual output poly phase step-down controller for ultra-low DCR sensing with digital power system management. Please see LTC®3884 data sheet for more detailed information. DC2283A powers up to default settings and produces power based on configuration resistors or with its non-volatile memory without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter. To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlay™ on-to your PC and use LTC’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on the fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.

Refer to Figure 1 for the proper measurement equipment setup and follow the procedure below. 1. With power off, connect the input power supply to VIN (7V – 14V) and GND (input return). 2. Connect the output loads between VOUT0/ VOUT1 and GND (Initial load: no load). Refer to Figure 1. 3. Connect the DVMs to the input and output. 4. Check the default jumper/switch position: JP1: OFF; JP4: OFF; JP5: INT; SW1: OFF; SW2: OFF. 5. Turn on the input power supply and adjust voltage to 12V; NOTE. Make sure that the input voltage does not exceed 14V. 6. Turn on the switches: SW1:ON; SW2:ON; 7. Check for the proper output voltages from VOUT1+ to VOUT1–. 8. Once the proper output voltage is established, adjust the loads within the operating range and observe the output voltage regulation, ripple voltage and other parameters. 9. Connect the dongle and control the output voltage from the GUI. See “LTpowerPlay Quick Start Guide” session for details. Notes: 1. As stated in the Description section, demonstration circuit 2283A provides an option to be configured as a dual-output converter. When the board is set up as a single-output converter (the default setup), four 0Ω shunt resistors are populated to short VOUT0 and VOUT1. Please follow Figure 1 to set up the connection of two loads to the output terminals to avoid board damage. – + 1mΩ + – LOAD0 (40A) 1mΩ + + – – VIN 7V TO 14V LOAD1 (120A) – + 1mΩ + VOUT – DC2447 F01 Figure 1. Proper Measurement Equipment Setup 2 dc2283af DEMO MANUAL DC2283A Quick Start Procedure 2. When measuring the output or input voltage ripple, do not use the long ground lead on the oscilloscope probe. See Figure 2 for the proper scope probe technique. Short, stiff leads need to be soldered to the (+) and (–) terminals of an output capacitor. The probe’s ground ring needs to touch the (–) lead and the probe tip needs to touch the (+) lead. + VOUT Connecting a PC to DC2283A You can use a PC to reconfigure the power management features of the LTC3884 such as: nominal VOUT, margin set points, OV/UV limits, temperature fault limits, sequencing parameters, the fault log, fault responses and other functionality. The DC1613A dongle may be plugged when VIN is present. – COUT GND Figure 2.
