Description
The FD2004 is a digital DC-DC controller designed to work with the FD1505 MOSFET driver IC. Current sharing allows multiple devices to be connected in parallel to source loads with very high current demands. Adaptive performance optimization algorithms improve power conversion efficiency across the load range. The Digital-DC™ technology enables a blend of power conversion performance and power management features.
