DEMO MANUAL DC2595A LTC3889EUKG 60V Dual Output Step-Down DC/DC Controller with Digital Power System Management DESCRIPTION Demonstration circuit 2595A is a high voltage, dual output step-down synchronous buck converter featuring the LTC(R)3889EUKG, a 60V dual-phase current mode controller. The LTC3889 has the PMBus interface and the power system management functions. The DC2595A uses discrete MOSFET as the power stage. The input range of this board is from 36V to 54V, and the default outputs are 12V/20A (VOUT0) and 24V/20A (VOUT1). DC2595A also has an on-board dynamic load circuit, which makes it easy for the customer to evaluate the transient performances. Please be aware that the DC2595A default connects VOUT0 (12V) to the LTC3889 EXTVCC pin through R168. As a result, the DRVCC can be adjusted to 6.3V, 7.4V or 9V by setting DRVSET to 0, 1 or 2 in LTpowerPlay(R). If you want to adjust VOUT0 to a voltage higher than 12V, R168 must be removed first to avoid damaging the IC. The DC2595A powers up to default settings and produces power based on configuration resistors or NVM without PERFORMANCE SUMMARY the need for any serial bus communication. This allows easy evaluation of the DC/DC converter aspects of the LTC3889. To fully explore the extensive power system management features of the parts, download the GUI software LTpowerPlay onto your PC and use LTC's I2C/ SMBus/PMBus Dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part onthe-fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.

Refer to Figure 2 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 C10 for CH0 and C26 for CH1. See Figure 3 for proper scope probe technique. 1. Make sure jumpers are in the following positions: JUMPER POSITION FUNCTION JP1 OFF Ext 5.5V (On-Board Bias Supply) for EXTVCC JP2 NC FAULT0B to FAULT1B JP3 NC RUN0 to RUN1 JP5 INT External or On-Board Pulse Generator for Transient Circuit JP6 OFF On-Board Pulse Generator On/Off 2. With power off, connect the input power supply to VIN and GND. Connect active load to the output. 2 3. Make sure both RUN switches (SW1, SW2) are OFF. 4. Set the input power supply between 36V to 54V; turn on the power at the input. Note: Make sure that the input voltage does not exceed 54V. 5. Turn on both SW1 (for RUN0), and SW2 (for RUN1) switches as desired. 6. Check for the correct output voltage from E5 to E6 for CH0, E7 to E8 for CH1. VOUT0 = 12.0V 0.5% (11.94V ~ 12.06V), VOUT1 = 24V 0.5% (23.88V ~ 24.12V). Note. If there is no output, temporarily disconnect the load to make sure that the load is not set too high. 7. Once the proper output voltage is 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 voltage from the GUI. See LTpowerPlay Quick Start Procedure section for details. UG-1383 Rev. 0 DEMO MANUAL DC2595A QUICK START PROCEDURE Connecting a PC to DC2595A You can use a PC to reconfigure the power management features of the LTC3889 such as: nominal VOUT, margin set points, OV/UV limits, temperature fault limits, sequencing parameters, the fault log, fault responses, GPIO and other functionality. The DC1613A dongle may be plugged in regardless of whether or not VIN is present. Dongle can be hot plugged. Figure 1. Demo Setup with PC for DC2595A Figure 2.

Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality. Legal Terms and Conditions By using the evaluation board discussed herein (together with any tools, components documentation or support materials, the "Evaluation Board"), you are agreeing to be bound by the terms and conditions set forth below ("Agreement") unless you have purchased the Evaluation Board, in which case the Analog Devices Standard Terms and Conditions of Sale shall govern. Do not use the Evaluation Board until you have read and agreed to the Agreement. Your use of the Evaluation Board shall signify your acceptance of the Agreement. This Agreement is made by and between you ("Customer") and Analog Devices, Inc. ("ADI"), with its principal place of business at One Technology Way, Norwood, MA 02062, USA. Subject to the terms and conditions of the Agreement, ADI hereby grants to Customer a free, limited, personal, temporary, non-exclusive, non-sublicensable, non-transferable license to use the Evaluation Board FOR EVALUATION PURPOSES ONLY.

Furthermore, the license granted is expressly made subject to the following additional limitations: Customer shall not (i) rent, lease, display, sell, transfer, assign, sublicense, or distribute the Evaluation Board; and (ii) permit any Third Party to access the Evaluation Board. As used herein, the term "Third Party" includes any entity other than ADI, Customer, their employees, affiliates and in-house consultants. The Evaluation Board is NOT sold to Customer; all rights not expressly granted herein, including ownership of the Evaluation Board, are reserved by ADI. CONFIDENTIALITY. This Agreement and the Evaluation Board shall all be considered the confidential and proprietary information of ADI. Customer may not disclose or transfer any portion of the Evaluation Board to any other party for any reason. Upon discontinuation of use of the Evaluation Board or termination of this Agreement, Customer agrees to promptly return the Evaluation Board to ADI. ADDITIONAL RESTRICTIONS. Customer may not disassemble, decompile or reverse engineer chips on the Evaluation Board. Customer shall inform ADI of any occurred damages or any modifications or alterations it makes to the Evaluation Board, including but not limited to soldering or any other activity that affects the material content of the Evaluation Board. Modifications to the Evaluation Board must comply with applicable law, including but not limited to the RoHS Directive. TERMINATION. ADI may terminate this Agreement at any time upon giving written notice to Customer. Customer agrees to return to ADI the Evaluation Board at that time. LIMITATION OF LIABILITY. THE EVALUATION BOARD PROVIDED HEREUNDER IS PROVIDED "AS IS" AND ADI MAKES NO WARRANTIES OR REPRESENTATIONS OF ANY KIND WITH RESPECT TO IT. ADI SPECIFICALLY DISCLAIMS ANY REPRESENTATIONS, ENDORSEMENTS, GUARANTEES, OR WARRANTIES, EXPRESS OR IMPLIED, RELATED TO THE EVALUATION BOARD INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTY OF MERCHANTABILITY, TITLE, FITNESS FOR A PARTICULAR PURPOSE OR NONINFRINGEMENT OF INTELLECTUAL PROPERTY RIGHTS.
