Page 2: Key Features
The ZL9024M uses ChargeMode™ control (ASCR) architecture, which responds to a transient load within a 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™... - Page 3 ZL9024MEVAL1Z 1. Overview Figure 1. ZL9024MEVAL1Z Block Diagram Recommended Equipment • DC power supply with two channels or two separate DC power supplies with minimum 6V/20A sourcing capacity and 6V/0.5A sourcing capabilities, respectively • Electronic load capable of sinking current up to 33A •...

Page 4: Functional Description
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. - Page 5 (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”.
- Page 6 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.
