SN51DP Datasheet: A Comprehensive Guide to Specifications, Pinouts, and Applications
Typical Applications
- LVDS video transmission (FPD-Link, flat-panel displays)
- High-speed data links between PCBs or modules
- Camera interfaces, serializers/deserializers (SerDes) front-ends
- Industrial communication over short differential pairs
2. Input Stage (LED)
- Forward voltage ~1.2–1.4 V (typical).
- Trigger current (IFT): ~5–10 mA max (some datasheets specify 15 mA max).
- Compatible with 3.3V or 5V logic directly with a current-limiting resistor (e.g., 220–470 Ω for 5V).
Part Number Breakdown: What Does SN51DP Mean?
Before diving into the datasheet details, let's decode the nomenclature:
- SN: Typically denotes the series (Sanken’s hybrid IC series).
- 51: Model identifier (indicates current rating and voltage parameters).
- D: Often refers to the package type or internal topology (in many Sanken parts, this relates to a TO-220 or similar isolated package).
- P: Usually indicates "Plastic package" or "Power" variant.
The SN51DP is generally a switching regulator IC capable of handling medium to high power. It is most commonly found in step-down (buck) converter topologies, CRT televisions (for horizontal deflection power), and industrial power modules.
Q2: Can I use the SN51DP in a boost (step-up) converter?
A: The datasheet primary application is buck. While theoretically possible, no official reference design exists for boost. Use a dedicated boost controller instead.
