The PT7671 ExcaliburTM high performance integrated switching regulator (ISR) is rated for up to 30 A. Housed in a 27-pin, space-saving, solderable copper package, the PT7671 delivers a higher output current than many modules of similar size. This makes it an ideal choice where both a high output current and minimum board space are desirable. The PT7671 operates from a +5-V input bus and produces a tightly regulated output voltage that is programmable over the range, 1.3 V to 3.5 V. The output voltage is selected via 5-bit input code, which is compatible with VRM specifications.
