TIDA-00718
適用於 CMOS 影像感測器的小尺寸、低雜訊和高 PSRR 電源參考設計
TIDA-00718
概覽
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.
特點
- Great transient response
- Ripple free 1.8 V and 1.2 V voltage rails
- Small form factor solution
- Cost efficient solution with only a few compensation components
- TIDA-00718 provides design guide and design files of the power management section.
