The TIDA-00718 reference design provides a small size and high input voltage ripple rejection power supply to provide a stable and clean voltage source for CMOS image sensors. In this design a main power rail of 5 V from battery, Power over Ethernet (PoE) or DC adaptor is regulated down to three voltage rails: 3.3 V, 1.8 V and 1.2 V.
This solution can be utilized in consumer electronics and commercial applications as IP Network Cameras, Analog Security Camera, Video Doorbell, Internet webcam and many more.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
