SCT2330CTVBR

Voltage Regulators - DC DC Switching Regulators Overview

The SCT2330CTVBR is a 3A synchronous buck converter from SCT with a 3.8V to 28V input range and TSOT23-6L package. It features a 400kHz switching frequency with ±6% spread spectrum, reducing EMI through a zero-ringing switch node design. Integrated high-side (80mΩ) and low-side (42mΩ) MOSFETs ensure high efficiency. The device supports Pulse Skip Mode (PSM) for a typical 25uA quiescent current at light loads. Key protections include output overvoltage, cycle-by-cycle peak current limit, and thermal shutdown at 160°C. It includes a 4ms soft-start and programmable UVLO.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated proprietary gate drive scheme eliminates switch node ringing to reduce high-frequency radiated EMI without compromising switching times.
• Supports Pulse Skip Mode (PSM) operation to achieve ultra-low quiescent current during light-load conditions.
• Features programmable enable threshold and under-voltage lockout (UVLO) thresholds with hysteresis for flexible system control.

Voltage Regulators - DC DC Switching Regulators Applications

• White home appliances
• Digital TV (DTV) and set-top boxes (STB)
• WiFi speakers and audio products

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C' in the part number SCT2330CTVBR against official datasheets, as it may denote a specific voltage rating or revision distinct from the standard SCT2330TVBR. Confirm the package type is TSOT23-6L. Ensure compatibility with your target input voltage range of up to 28V. Check for any regional qualification requirements if applicable to your deployment environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3A continuous output current is required within a 28V maximum input constraint. It is suitable for designs prioritizing electromagnetic interference reduction through spread spectrum and zero-ringing techniques. Choose this over higher voltage variants if the system input does not exceed 28V, as it offers optimized performance for that specific range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the SCT2330 family of synchronous buck converters manufactured by SCT (Xinzhou Technology). It shares architectural similarities with the SCT2330TVBR but is distinguished by the 'C' suffix, which typically indicates a specific input voltage window or manufacturing lot variation. It complements other SCT power management solutions like the SCT2320 series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

SCT2330TVBR is a direct functional substitute within the same family. For broader replacements, consider SCT2320TVBR for 2A applications or SCT2331/2332 variants if different pinouts or features are needed. Verify BOM compatibility and thermal performance when substituting.
