Patented design enables board designers to place the new AS3721 PMIC and applications processor further apart to reduce hotspot intensity.
Ams AG, a provider of high performance analog ICs and sensors, has introduced the AS3721, a power management IC with a remote-feedback circuit that helps manage the thermal stress of applications processors in space-constrained devices.
The AS3721 PMIC enables a compact remote feedback path from the processor to the IC’s integrated DC-DC controllers, according to ams AG. A patent-pending design innovation by ams reduces the number of wire connecting the PMIC to the processor, enabling the two devices to be placed further apart in the board layouts of space-constrained devices such as smartphones, tablets and notebooks.
“This [placement] dramatically reduces the size and intensity of the hotspot around the processor compared to conventional power architectures in which the processor and PMIC, both handling high currents simultaneously, must be located side-by-side,” the company said.
In addition, when combined with new AS3729 point-of-load regulators from ams, the “highly-integrated AS3721 provides a complete power management system that offers a fast response to load transients for reliable processor performance, high efficiency, and flexible board layout,” the company said.
