Application Note 2041 Author: Marty Pandola ZL6100EVAL2Z Dual Channel Evaluation Board Description Features 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. • 30A Single-phase and 60A Dual-phase Rails The ZL6100EVAL2Z platform is a 6-layer board with two power rails. One rail is a single phase, 30A power rail. The other rail is a dual phase, 60A power rail demonstrating the current sharing capability of the ZL6100. Target Specifications A USB to SMBus adapter board can be used to connect the eval board to a PC. The PMBus command set is accessed by using the Zilker Labs PowerNavigator™ evaluation software from a PC running Microsoft Windows. • Optimized for Efficiency • Configurable Through SMBus • Onboard Enable Switch • Power Good Indicators • VIN = 12V • VOUT1 = 1.8V/60A max • VOUT2 = 1.5V/30A max • fsw = 300kHz • Efficiency: 90% at 50% load • Output Ripple: ±1.5% • Dynamic response: ±3% (50%-70%-50% load step, di/dt = 2.5A/µs) • Board Temperature: +25°C VIN P3 EN SYNC P1 V OUT2 ZL6100 SMBus DDC ENABLE SW1 EN SYNC ZL6100 P2 V OUT1 SMBus DDC EN SYNC ZL6100 SYNC DDC SMBus TRACK SMBus DDC J10 VTRK J11 PG SYNC DDC SMBus PG FIGURE 1.

Application Note 2041 Functional Description The ZL6100EVAL2Z provides all circuitry required to demonstrate the features of the ZL6100. The ZL6100EVAL2Z 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. All features of the ZL6100 such as current sharing, softstart delay and ramp times, supply sequencing, voltage tracking, and voltage margining are available on this evaluation board. For voltage tracking, the board is set up for the single phase rail (VOUT2) to track the dual phase rail (VOUT1). Contact the Zilker Labs sales office for configuring the board for other tracking combinations. Figure 1 shows a functional block diagram of the ZL6100EVAL2Z 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. The hardware enable function is controlled by a toggle switch on the ZL6100EVAL2Z board. The power good (PG) LEDs indicate the correct state of PG when external power is applied to the ZL6100EVAL2Z board. (Note: If a USB board is connected to the ZL6100EVAL2Z and no power is applied to the board, the PG LEDs will turn on even though the power rails are not enabled.) 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. Figures 2 and 3 show the two phases of the 60A circuit. Figure 4 shows the single phase operational circuit. The circuit consists of the ZL6100 IC with its minimal component count to realize a 30A buck converter. The board layout has been optimized for thermal performance. Figure 5 is the Interface and Figure 9 SMBus address selection circuitry. been pre-configured as described in this document, but the user may modify the operating parameters through the eval software or by loading a predefined scenario from a configuration file. Use the mouse-over pop-ups for PowerNavigator help. Refer to Zilker Labs application note AN2033 “PMBus™ Command Set DDC Products”, Intersil Corporation, 2009 for PMBus details. The ENABLE switch can then be moved to “ENABLE” and the ZL6100EVAL2Z 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+/VOUT- for each channel 3. Connect power supply to VIN+/VIN- (supply turned off) 4. Turn power supply on 5. Set ENABLE switch to “ENABLE” 6. Monitor ZL6100EVAL2Z board operation using an oscilloscope USB (PMBus) Operation 1. Set ENABLE switch to “DISABLE” 2. Apply load to VOUT+/VOUT- for each channel 3. Connect power supply to VIN+/VIN- (supply turned off) 4. Turn power supply on 5. Insert the Zilker Labs Eval Kit CD 6. Connect USB to SMBus adapter board to J10 of ZL6100EVAL2Z 7. Connect supplied USB cable from computer to USB to SMBus adapter board Operation a) Upon first-time connection, the Found New Hardware Wizard will appear. PMBus Operation b) Windows XP users: Select ‘No’ at prompt to search the Internet for drivers. 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 ZL6100EVAL2Z software using the CD included in the ZL6100EVAL2Z kit. For board operation, connect the included USB-to-SMBus adapter board to J10 of the ZL6100EVAL2Z 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. c) 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 ZL6100EVAL2Z board using PMBus commands in the evaluation software 11.Test the ZL6100EVAL2Z operation using an oscilloscope and the evaluation software. The evaluation software allows modification of all ZL6100 PMBus parameters. Each of the ZL6100 devices have 2 AN2041.0 September 11, 2009 Board Schematics 3 Application Note 2041 FIGURE 2.
