Overview
Description
Easily evaluate the features of the ISL8270M digital DC/DC PMBus 25A module, including compensation-free ChargeMode™ control, soft-start delay and ramp times, supply sequencing, and voltage margining.
The ISL8270MEVAL1Z evaluation board is a 3in x 4.5in 4-layer FR4 board with 2 oz. copper in all layers. This evaluation board comes with a placeholder for pin-strap resistors to adjust output voltage, switching frequency, input undervoltage (UVLO) protection threshold, and device PMBus address. Easily program or change configuration options such as soft-start and fault limits via the PMBus compliant serial bus interface.
For sequencing evaluation, this evaluation board can be connected to any Renesas digital module evaluation board that supports the Digital-DC™ (DDC) bus.
The ISLUSBEVAL1Z USB to PMBus™ adapter is provided with this evaluation kit, 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.
