Description
The SCT2630STER is a high-efficiency, synchronous step-down DC-DC converter from Silicon Mitus, designed for battery-powered and portable devices.
### Key Features:
- Input Voltage: 4.5V to 18V
- Output Voltage: Adjustable (0.6V to 15V)
- Max Output Current: 3A
- High Efficiency (up to 95%) with synchronous rectification
- Fixed 500kHz Switching Frequency
- Protections: Overcurrent (OCP), Overvoltage (OVP), Thermal Shutdown (TSD)
- Compact TSOT-23-6 Package
### Applications:
- Portable electronics (tablets, drones)
- IoT devices
- Industrial & consumer systems
It offers low quiescent current (30μA) for improved battery life and fast transient response, making it ideal for space-constrained, power-sensitive designs.
For detailed specs, refer to the datasheet.
