Expanding the company’s power-manager family, the AS3722 PMIC and AS3728 power stages supply take on multi-core ARM processors. The AS3722 provides a complete power-control solution for Nvidia’s Tegra K1 mobile system-on-chip (SoC) while the AS3728 8A, high-voltage power stage complements the AS3722’s high-current dc/dc controllers. The AS3728 provides for a streamlined power architecture in embedded systems, since it can supply the high current required by processor cores directly from a 12V power rail. The AS3722 PMIC and multiple AS3728 devices power the Tegra K1 processor in Nvidia’s Jetson TK1 reference design board. The Tegra K1, Nvidia’s latest mobile SoC, features a quad-core ARM Cortex-A15 CPU and 192 CUDA graphics processing cores. The AS3722 comes in a 124-pin CTBGA package measuring 8 mm x 8 mm x 0.5 mm or a 108-pin CSP measuring 4.8mm x 3.6 mm x 0.4 mm. The AS3728 resides in a 2.4 mm x 1.6 mm x 0.4 mm package that can install on a standard 4-mil PCB without the need for vias. The AS3722 is priced at $4.12 each/1,000 and the AS3728 is $0.54 each/1,000.
