Présentation
Description
The SC8933QFER is a synchronous buck controller designed for high-efficiency DC-DC voltage regulation. Key features include:
- Wide Input Range: Supports 4.5V to 36V, suitable for industrial, automotive, and telecom applications.
- Adjustable Output: Configurable via external resistors, typically down to 0.8V.
- High Efficiency: Uses synchronous rectification and supports up to 95% efficiency.
- Programmable Switching Frequency: Ranges from 100kHz to 1MHz, allowing flexibility in design.
- Protections: Includes overcurrent (OCP), overvoltage (OVP), undervoltage lockout (UVLO), and thermal shutdown.
- Package: QFN-16 for compact PCB layouts.
Ideal for point-of-load (POL) converters, it balances performance and cost in power supply designs.
