The ZL8800 is a digital power conversion and management IC that combines an efficient step-down DC/DC converter with key power and thermal management functions in a single package. The ZL8800 incorporates compensation-free ChargeMode control to achieve single-cycle transient response.

The ZL8800-2PH-DEMO1Z demonstration board is a 6-layer board used to demonstrate a two-phase 60A synchronous buck converter. Sequencing, margining, plus other features can be evaluated using this demonstration board.

The ZL8800-2CH-DEMO1Z dual channel DC/DC digital controller demo board is also available.


  • Two-phase 60A synchronous buck converter with compensation-free ChargeMode control
  • Designed to be easy to use and modify. Optimized for a small circuit footprint and dynamic response
  • Configurable through PMBus
  • VIN range of 4.5V to 14V, VOUT adjustable from 0.54V to 5.5V
  • Enable switches and power-good indicators


  • Servers/Storage equipment
  • Telecom/Datacom equipment
  • Power supplies (memory, DSP, ASIC, FPGA)
