Power Integrations RDK-851 Power Management IC Development Tools
Power Integrations RDK-851 Power Management IC Development Tools are three-phase inverter reference design boards based on the BridgeSwitch motor driver IC. The IC targets high-voltage BLDC fan applications. The inverter board drives a three-phase BLDC fan motor up to 0.22ARMS motor current with >93% efficiency without an external heat sink. The design has a complete inverter stage with a control input interface to facilitate various control schemes.Features
