Application Note 1493 ZL6100EVAL1Z Evaluation Board The ZL6100 is an integrated mixed-signal power conversion and management IC that combines an efficient step-down DC/DC converter with key power and thermal management functions in a single package. The ZL6100 incorporates current sharing and adaptive efficiency-optimization algorithms to provide a flexible, efficient power IC building block. The ZL6100EVAL1Z platform is a 4-layer board demonstrating a 15A synchronous buck converter. Sequencing, tracking, margining, plus other features can be evaluated using this board. A USB to SMBus adapter board can be used to connect the evaluation board to a PC. The PMBus command set is accessed by using the Zilker Labs PowerNavigator™ evaluation software from a PC running Microsoft Windows. Key Features • 15A Synchronous Buck Converter • Optimized for Small Circuit Footprint and Dynamic Response • Configurable through SMBus • Onboard Enable Switch • Power-Good Indicator Ordering Information PART NUMBER DESCRIPTION ZL6100EVAL1Z ZL6100 Evaluation Kit (EVB, USB Adapter, Cable, Software) Target Specifications • VIN = 12V • VOUT = 1.2V/15A (20A max) • fsw = 400kHz • Efficiency: 86% at 10A • Output Ripple: ±1% • Dynamic Response: ±3% (50% to 100% to 50% load step, di/dt = 2.5A/µs) • Board Temperature: +25°C Functional Description The ZL6100EVAL1Z provides all circuitry required to demonstrate the features of the ZL6100. The ZL6100EVAL1Z has a functionally-optimized ZL6100 circuit layout that allows efficient operation up to the maximum output current. Power and load connections are provided through plug-in sockets. A majority of the features of the ZL6100 such as soft-start delay and ramp times, supply sequencing, voltage tracking, and voltage margining are available on this evaluation board. For voltage tracking and sequencing evaluation, the board can be connected to any other Zilker Labs evaluation board that supports the Digital DC (DDC) bus. Figure 1 shows a functional block diagram of the ZL6100EVAL1Z board. The SMBus address is selectable through a jumper on the top side of the board. All power to the board (VIN and I2C bus) must be removed before changing the jumpers.

Application Note 1493 The hardware enable function is controlled by a toggle switch on the ZL6100EVAL1Z board. The power-good (PG) LEDs indicate the correct state of PG when external power is applied to the ZL6100EVAL1Z board. The right angle headers at opposite ends of the board are for connecting a USB to SMBus adapter board or for daisy chaining of multiple evaluation boards. Figure 2 shows the operational circuit. The circuit consists of the ZL6100 IC with its minimal component count to realize a 15A buck converter. The board layout has been optimized for thermal performance. Figure 3 is the board interface circuitry and Figures 4 through 8 demonstrate the PCB Board Layout, which includes the board fabrication notes. 4. Connect supplied USB cable from computer to USB to SMBus adapter board (Optional: provides power for onboard LED’s so that LED power does not detract from efficiency measurement) 5. Connect power supply to VIN+/VIN- (supply turned off) 6. Turn power supply on 7. Set ENABLE switch to “ENABLE” 8. Monitor ZL6100EVAL1Z board operation using an oscilloscope USB (PMBus) Operation 1. Set ENABLE switch to “DISABLE” The Bill of Materials (BOM) and configuration file are also included for reference beginning on page 10. 2. Apply load to VOUT+/VOUT3. Connect power supply to VIN+/VIN- (supply turned off) Operation 4. Turn power supply on 5. Insert the Zilker Labs Eval Kit CD PMBus Operation The ZL6100 utilizes the PMBus protocol. The PMBus functionality can be controlled via USB from a PC running the PowerNavigator evaluation software in a Windows XP or Windows 2000/NT operating system. Install the evaluation software using the CD included in the ZL6100EVAL1Z kit. For board operation, connect the included USB-to-SMBus adapter board to J10 of the ZL6100EVAL1Z board. Connect the desired load and an appropriate power supply to the input and connect the included USB cable to the PC running the PowerNavigator evaluation software. Place the ENABLE switch in “DISABLE” and turn on the power. The evaluation software allows modification of all ZL6100 PMBus parameters. The ZL6100 device on the board has been pre-configured as described in this document, but the user may modify the operating parameters through the evaluation software or by loading a predefined scenario from a configuration file. 6. Connect USB to SMBus adapter board to J10 of ZL6100EVAL1Z 7. Connect supplied USB cable from computer to USB to SMBus adapter board. - Upon first-time connection, the Found New Hardware Wizard will appear. - Windows XP users: Select ‘No’ at prompt to search the Internet for drivers. - Follow the steps on the screen to install the drivers from the CD. 8. Install the PowerNavigator evaluation software by running setup.exe from the PowerNavigator_installer folder on the CD. 9. Set ENABLE switch on EVB to “ENABLE” 10.Monitor and configure the ZL6100EVAL1Z board using PMBus commands in the evaluation software 11.Test the ZL6100EVAL1Z operation using an oscilloscope and the evaluation software. Use the mouse-over pop-ups for PowerNavigator help. Refer to Zilker Labs application note AN2033 for PMBus details. The ENABLE switch can then be moved to “ENABLE” and the ZL6100EVAL1Z board can be tested. Alternately, the PMBus ON-OFF CONFIG and OPERATION commands may be used. Quick Start Guide Stand Alone Operation 1. Set ENABLE switch to “DISABLE” 2. Apply load to VOUT+/VOUT3. Connect the USB to SMBus adapter board to J10 of ZL6100EVAL1Z (Optional: provides power for onboard LED’s so that LED power does not detract from efficiency measurement) 2 AN1493.0 September 4, 2009 ZL6100EVAL1Z BOARD SCHEMATICS JP1 1 2 3 4 D PG_0 EN PG_0 Rework across Q1/1 and Q1/2 HW_EN XTEMP R1 100k Temperature Measurement place near inductor C50 100p VIN Q1 2N3904 1 C1 2.2u L1 1000Z C2 10u C3 10u C4 10u C5 10u JP2 XX1 2 C6 10u SG SG V25 V25 DDC C10 10u CFG DLY0 DLY1 PG 5 6 7 8 36 35 34 33 32 31 30 29 28 R10 11.0k R16 16.2k VSENVSEN+ 1 3 5 7 9 V1 V0 2 4 6 8 10 SA1 J2 C11 Q2 FDMS8692 GH L2 360n SW VOUT 5 6 7 8 4 GH SW 0 GL Q3 FDMS8670AS GL C17 R6 C27 10u 10u XX3 C12 680u C13 680u C45 680u C8 100u C9 100u C15 100u C16 100u C44 100u + VOUT - XX4 ISENA U1 P1 499 1u C26 VOUT XX2 1u 4 SGND VDD BST GH SW PGND GL VR ISENA ISENB 37 ZL6100 FC0 FC1 V0 V1 UVLO SS VTRK VSEN+ VSEN- DGND SYNC SA0 SA1 ILIM0 ILIM1 SCL SDA SALRT SS VTRK SA0 Address Selection 0x20 R11 19.6k 0x21 R12 21.5k 0x22 R13 23.7k 0x23 R14 26.1k 0x24 R15 28.7k 0 R7 1.82k ISENB XX5 Ground Unification SG B FC0 FC1 SS VTRK R4 ILIM0 ILIM1 SCL SDA SALRT 27 VDD 26 BST R5 25 24 23 22 VR 21 ISENA 20 ISENB 19 Application Note 1493 ILIM0 ILIM1 SCL SDA SALRT SYNC D1 MBR0540 10 11 12 13 14 15 16 17 18 SYNC 1 2 3 4 5 6 7 8 9 PG DLY1 DLY0 EN CFG MGN DDC XTEMP V25 SG 3 2 1 C CFG DLY0 DLY1 PG 3 2 1 3 DDC GND GND C46 100n VOUT- R17 34.8k R18 VSENC29 100n Note 2 VSEN+ 1000Z Note 1 VOUTVOUT+ R19 VOUT+ 1000Z SG SG SG SG SG ZILKER LABS, CONFIDENTIAL AND PROPRIETAR A 4301 WESTBANK DRIVE Notes: 1) Frequency response measurement components.
