PWM controller suits high current applications
1 min read
Intersil has announced the ZL8801; a dual phase, DC/DC digital PWM controller.
The device is suitable for higher current applications ranging from 40 to 100A. With the ability to current share across multiple devices, its range can be extended up to 300 amps for high end FPGAs and ASICs employed in densely populated power supplies in servers, storage equipment and basestations.
Used in conjunction with Intersil's PowerNavigator graphical user interface, the ZL8801 is said to simplify system power conversion and speed the design process.
The device also utilises the company's patented ChargeMode control loop architecture to deliver superior transient response compared to today's analogue controllers.
The ZL8801's fully digital control loop corrects errors cycle by cycle, eliminating the need for compensation. Its high control loop bandwidth reduces the amount of output capacitance needed to meet the latest transient requirements of high end FPGAs and ASICs, resulting in a smaller board size and lower bill of materials cost.
