Description Features The ZL2006 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 ZL2006 incorporates current sharing and adaptive efficiencyoptimization algorithms to provide a flexible, efficient power IC building block. • • • • • The ZL2006EV2 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 ZL2006. 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. 30A single-phase and 60A dual-phase rails Optimized for efficiency Configurable through SMBus Onboard enable switch Power good indicators Target Specifications • • • • • • • VIN = 12 V VOUT1 = 1.8 V / 60 A max VOUT2 = 1.5 V / 30 A max fsw = 300 kHz Efficiency: 90% at 50% load Output ripple: ±1.5% Dynamic response: ±3% (50%-70%-50% load step, di/dt = 2.5 A/μs) • Board temperature: 25°C Figure 1. ZL2006EV2 Block Diagram ZL2006EV2 Functional Description The ZL2006EV2 provides all circuitry required to demonstrate the features of the ZL2006. The ZL2006EV2 has a functionally-optimized ZL2006 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 ZL2006 such as current sharing, soft-start 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 ZL2006EV2 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 ZL2006EV2 board. The power good (PG) LEDs indicate the correct state of PG when external power is applied to the ZL2006EV2 board. (Note: If a USB board is connected to the ZL2006EV2 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. Operation PMBus Operation The ZL2006 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 ZL2006EV2 software using the CD included in the ZL2006EV2 kit. For board operation, connect the included USBto-SMBus adapter board to J10 of the ZL2006EV2 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 ZL2006 PMBus parameters. Each of the ZL2006 devices have 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 AN33 [2] for PMBus details. The ENABLE switch can then be moved to “ENABLE” and the ZL2006EV2 board can be tested. Alternately, the PMBus ON-OFF CONFIG and OPERATION commands may be used. Figure 2 and Figure 3 show the two phases of the 60A circuit. Figure 4 shows the single phase operational circuit. The circuit consists of the ZL2006 IC with its minimal component count to realize a 30 A buck converter. The board layout has been optimized for thermal performance. Figure 5 is the Interface and Figure 9 SMBus address selection circuitry. 2 ZL2006EV2DSR3.0 ZL2006EV2 Quick Start Guide Stand Alone Operation USB (PMBus) Operation 1.

Efficiency The measured input power includes the quiescent current for all three controllers on the evaluation board and is included in the efficiency measurement for the separate channels. Adaptive diode emulation and adaptive frequency modes are disabled for these efficiency measurements.
