AR0246 Power Tree

AR0246

The AR0246 Hyperlux™ LH is a 2 MP BSI CMOS image sensor featuring 1920 × 1080 Full HD resolution at up to 60 fps. Designed for superior low-light performance, it combines enhanced NIR sensitivity, eHDR/HDR support, Wake-on-Motion (WOM), and ultra-low-power operation. Its advanced dynamic range capabilities and compact 1/4-inch format make it ideal for security cameras, smart vision systems, IoT devices, and industrial imaging applications.

Cost-effective Power Delivery Design for AR0246 Image Sensor

The AR0246 Hyperlux™ LH 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 voltage domains. 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 implementations. In 48 V industrial systems, a FAN65004C 6 A buck regulator generates an intermediate rail that feeds the downstream regulators. 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 helps maximize low-light performance, dynamic range, and overall image quality.
