The PT6940 ExcaliburTM power modules are a series of high-efficiency dual-output regulators, housed in a solderable space-saving package. The dual output is ideal for DSP applications that require a second voltage source for a processor core.
Both outputs from the PT6940 regulator modules are rated to deliver a full 6A load current simultaneously, and are internally sequenced to comply with the power-up requirements of popular DSP ICs.
Each output can be independently adjusted with a single external resistor, and incorporates an output sense to compensate for voltage drop between the regulator and load. A short-circuit load fault at either output will result in the coordinated shutdown of both voltages
