ZL8801-xPH-DEMO1Z

2 or 4-Phase PMBus™ ChargeMode™ Control DC/DC Digital Controller Demonstration Boards

Description

The ZL8801 is a dual-phase digital DC/DC controller optimized for current sharing. As many as four ZL8801s can be operated in parallel to provide even phase counts between two and eight phases. The ZL8801 incorporates compensation-free ChargeMode™ control to achieve single-cycle transient response. ZL8801 can also be used with the ISL99140 40A DrMOS power module to simplify layout and allow for extra design flexibility.

The ZL8801-2PH-DEMO1Z demonstration board is a 6-layer board used to demonstrate a 2-phase 80A synchronous buck converter. Sequencing, margining, plus other features can be evaluated using this demonstration board.

The ZL8801-4PH-DEMO1Z demonstration board is a 6-layer board configured as a 4-phase 160A synchronous buck converter. Sequencing, margining, fault spreading, and other features can be evaluated using this board.

A USB to PMBus™ adapter module is used to connect the demonstration board to a host PC running Microsoft Windows.
