AR0830 Power Design

AR0830

The AR0830 Hyperlux™ LP is an 8.3 MP stacked BSI CMOS image sensor featuring 3840 × 2160 (4K) resolution at up to 60 fps. Designed for ultra-low-power operation, it combines enhanced 850 nm and 940 nm NIR sensitivity, Wake-on-Motion (WOM), HDR/eDR support, and flexible subsampling modes for efficient edge imaging. Its compact design makes it ideal for smart cameras, video doorbells, video conferencing, retail analytics, machine vision, and AR/VR applications.

Cost-effective Power Delivery Design for AR0830 Image Sensor

The AR0830 Hyperlux™ LP image sensor requires dedicated analog, digital core, and I/O supply rails. For 5 V input systems, the power tree uses NCP161, NCP114, T30LMPSR165, and NCP163 low-noise LDO regulators to generate the required rails. For 5 V to 18 V power-over-coax applications, the highly integrated NCV92310 PMIC provides power conversion and sequencing in a single device, simplifying remote camera designs. In 48 V industrial systems, a FAN65004C 6 A buck regulator generates an intermediate supply rail that feeds the downstream LDOs. Additional configurations support integration with the AP1302 ISP for local or remote image processing. MCU-controlled sequencing ensures proper power-up and power-down timing, while the combination of efficient power conversion and ultra-low-noise regulation maximizes image quality and power efficiency.
