Evaluation Board

Jan 29, 2018

1. Overview

The ZL9024M is a 33A step-down DC/DC power supply module with an integrated digital PWM controller, single-phase synchronous power switches, inductors, and passives. Only input/output capacitors and minimal passives are needed to finish the design. 33A of continuous output current can be delivered without the need for airflow or a heatsink. The ZL9024M uses ChargeMode™ single switching cycle.

The ZL9024MEVAL1Z evaluation board is a 3inx4.5in 6-layer FR4 board with 2oz. copper on surface layers and 1oz. copper on buried layers. This evaluation board comes with placeholders for pin-strap resistor population to adjust output voltage, switching frequency, and device PMBus™ address. More configurations, such as sequencing, DigitalDC™ (DDC) bus configuration and fault limits can be easily programmed or changed through the PMBus compliant serial bus interface.

The optional ZLUSBEVAL3Z (USB to PMBus adapter) is provided with this evaluation board, which connects the evaluation board to a PC to activate the PMBus communication interface. The PMBus command set is accessed by using the PowerNavigator™ evaluation software from a PC running Microsoft Windows. The ZL9024MEVAL1Z can operate in pin-strap mode without needing the ZLUSBEVAL3Z adapter or PMBus communication.

ZL9024MEVAL1Z 2. Functional Description

2. Functional Description

The ZL9024MEVAL1Z provides all circuitry required to evaluate the features of the ZL9024M. A majority of the features of the ZL9024M, such as compensation-free ChargeMode control, soft-start delay and ramp times, supply sequencing and voltage margining are available on this evaluation board. For sequencing evaluation, the board can be connected to any Intersil digital module evaluation board that supports the DDC bus.

2.1 Operating Range

By default, the ZL9024M is configured to operate at V 4V. The board can also support a wider operating range to meet the requirements of specific applications. V be adjusted from 0.6V to 1.5V. The load current range is from 0A to 33A. The f tuned. However, to ensure sufficient stability margins, switching frequency and output capacitors can be selected using the “ZL9024M Design Guide Matrix and Output Voltage Response” table in the ZL9024M

The ZL9024MEVAL1Z is capable of handling a 0A to 33A output current transient, in which the slew rate is less than 2A/µs, such as electronic load. If the slew rate exceeds 2A/µs, then it may be necessary to increase the output capacitance or change VOUT_OV_FAULT_LIMIT and VOUT_UV_FAULT_LIMIT values for proper operation. Refer to “

If external synchronization is used, connect the SYNC test point to the external clock. Note that the external clock signal should be active before the module is enabled.

PMBus option.

(1) Install PowerNavigator software from the following website: www.intersil.com/powernavigator

(2) Set the ENABLE switch to “DISABLE”.

(3) Connect the load to the VOUT lug connectors (J7 and J8).

(4) Connect the power supply to the VIN connectors (J3 and J4). Make sure the power supply is not enabled

when making the connections.

(5) Connect the VDD voltage supply to the VDD connectors (J9 and J10). Make sure the power supply is not

enabled when making the connections.

(6) Connect the ZLUSBEVAL3Z dongle (USB to PMBus adapter) to the ZL9024MEVAL1Z board using the

6-pin male connector labeled “PMBus DONGLE IN”.

(7) Turn the power supply on.

(8) Connect the supplied USB cable from the computer USB port to the ZLUSBEVAL3Z dongle.

(9) Start PowerNavigator.

(10) It is optional to load a predefined setup from a configuration file using PowerNavigator. The ZL9024M

device on the board operates in pin-strap mode from factory default, but the user can modify the operating parameters through the evaluation software or by loading a predefined set-up from a configuration file. A sample “

Configuration File” on page 7 is provided and can be copied to a plain text editor to make desired

changes. The default pin-strap configurations will be overwritten if a user-defined configuration file is loaded.

(11) Set the ENABLE switch to “ENABLE”. Alternatively, the PMBus ON_OFF_CONFIG and OPERATION

commands may be used from PowerNavigator to allow PMBus Enable.

(12) Monitor and configure the ZL9024MEVAL1Z board using the PMBus commands in the evaluation

software. To store the configuration changes, disable the module and use the command STORE_USER_ALL. To restore factory default settings, disable the module and use the command RESTORE_FACTORY and STORE_USER_ALL.

(13) For sequencing with the Digital-DC Bus (DDC) or to evaluate multiple Renesas digital power products

using a single ZLUSBEVAL3Z dongle, the ZL9024M can be daisy chained with other digital power evaluation boards. The PMBus address can be changed by placing a 1% standard 0603 resistor at the R placeholder location on the bottom layer. Refer to the “SMBus Address Resistor Selection” table in the

ZL9024M

datasheet for recommended values.

3.1 V

Transient Response Check

OUT

The ZL9024MEVAL1Z board has a built-in transient load test circuit (see the schematic in Figure 2) allowing transient load with a high slew rate. A 100A N-Channel MOSFET (Manufacturer PN: BSC010NE2LSI) is connected across VOUT and PGND next to the remote voltage sensing location. A 10mΩ current-sense resistor R

is used to monitor the drain-to-source current of the MOSFET. For a transient load test, inject the gate drive

pulse signal at J12. The load current can be monitored through J13. Because the MOSFET will operate in the saturation region instead of the linear region when the gate turn-on signal is applied, the pulse width and duty cycle of the gate signal must be limited small enough to avoid MOSFET overheating (recommended duty cycle should be less than 2%). The amplitude of the gate driver pulse voltage can be adjusted to obtain a desired transient load current step size.

Figure 2. Schematic for Transient Load Measurement

3.2 Thermal Considerations and Current Derating

Board layout is critical to make the module operate safely and deliver maximum allowable power. To work in the high temperature environments and carry large currents, the board layout needs to be carefully designed to maximize thermal performance. To achieve this, select enough trace width, copper weight, and the proper connectors.

The ZL9024MEVAL1Z evaluation board is designed to run at 33A at room temperature without additional cooling systems needed. However, if the output voltage is increased or the board is operated at elevated temperatures, then the available current is derated. Refer to the derated current curves in the ZL9024M maximum output current the evaluation board can supply.  module to measure peak junction temperature.
