SCT9320STDR

The SCT9320STDR is a synchronous buck converter from Semtech, designed for high-efficiency, step-down DC-DC conversion. Key features include:
- Input Voltage Range: 4.5V to 18V
- Output Current: Up to 20A
- Switching Frequency: Adjustable (300kHz to 1MHz)
- Efficiency: Up to 95% (with integrated MOSFETs)
- Protections: Overcurrent, overtemperature, and undervoltage lockout (UVLO)
It uses a current-mode control architecture for fast transient response and stable operation. The PowerStage™ integration reduces external components, simplifying PCB design.
Applications:
- Point-of-load (POL) supplies
- FPGAs, ASICs, and processors
- Networking and telecom equipment
Available in a 5mm × 6mm QFN package, it’s optimized for space-constrained designs.

The SCT9320STDR is a dual N-channel MOSFET in an 8-pin DFN (3x3mm) package.
Pin Functions:
1. Pins 1, 5, 6, 8: Drain (D) for both MOSFETs (connected internally).
2. Pins 2, 4: Gate (G) for MOSFET 1 and MOSFET 2, respectively.
3. Pins 3, 7: Source (S) for MOSFET 1 and MOSFET 2, respectively.
Key Features:
- 30V drain-source voltage (VDS)
- 20A continuous drain current (ID) per channel
- Low on-resistance (RDS(on) = 4.5mΩ max)
- Optimized for synchronous buck converters and power management.
This compact, high-efficiency MOSFET is commonly used in DC-DC converters, motor drives, and load switches.

The SCT9320STDR is a DFN-8 (3x3) package type. It features a dual flat no-lead (DFN) design with 8 pins and dimensions of 3mm x 3mm, making it compact for space-constrained applications. This package is surface-mountable, offering good thermal and electrical performance.
