Step-down DC-DC Controller
with 3A MOSFET Drivers
|
|
The ZL2005 is an innovative digital power conversion IC that combines a compact, efficient, synchronous buck controller, adaptive drivers and key power management functions in one tiny 6 x 6 mm package. It provides flexibility and scalability while decreasing board space and design complexity. Zilker Labs’ Digital-DC technology delivers highly-efficient performance with integrated power management capabilities and eliminates the need for programming. The ZL2005's flexible, scalable architecture allows a single device to be used in applications requiring a wide range of input/output voltages and load currents.
The ZL2005's high integration makes it ideal for space-restricted high-current applications. It can be used with other Digital-DC devices to provide a complete power system design for systems requiring multiple power domains on a single PCB.
