ZL8801-4PH-DEMO1Z, Demonstration Board for ZL8801 4-Phase PMBus ChargeMode Control DC/DC Digital Controller

ZL8801-4PH-DEMO1Z, Demonstration Board for the ZL8801 is a dual-phase digital DC to DC controller optimized for current sharing. As many as 4 ZL8801 can be operated in parallel to provide even phase counts between 2 and 8 phases. The ZL8801 incorporates compensation-free ChargeMode control to achieve single-cycle transient response. The ZL8801 supports a wide range of output voltages (0.54 to 5.5V) operating from input voltages between 4.5V and 14V. The ZL8801-4PH-DEMO1Z evaluation 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
