STCF07PNR

Overview

The STCF07PNR is a DC-DC regulator IC designed for LED driver applications, specifically targeting camera flash systems. It integrates step-down (buck) and step-up (boost) topologies with internal switches to manage power conversion efficiently. The device supports an output voltage range of 2.5 V to 5.3 V and delivers an output current of up to 1 A in flash mode. Operating at a frequency of 1.8 MHz, it ensures precise regulation while maintaining low supply current characteristics suitable for portable electronics.

Feature Summary

• Integrates buck and boost DC-DC converter topologies within a single package
• Includes internal power switches for simplified circuit design
• Optimized for high-frequency operation to reduce external component size
• Designed specifically for high-current camera flash LED driving

Applications

• Camera flash lighting systems
• Portable electronic devices requiring LED illumination
• Smartphone camera modules
• Compact imaging equipment

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm availability through authorized distributors as stock may be limited. Ensure the 16-QFN package matches your PCB footprint requirements. Check that the operating temperature range meets your environmental specifications. Validate compatibility with existing system voltage rails.

Selection Notes

Choose this regulator when a combined buck-boost solution is required for LED flashes. Consider the 1A current limit for peak brightness needs. Evaluate the 1.8MHz switching frequency against EMI constraints. Assess the 16-QFN package dimensions for space-constrained layouts. Compare efficiency metrics against alternative linear drivers for battery life optimization.

Part Context

This part belongs to STMicroelectronics' LED driver portfolio, focusing on power management for visual indicators. It complements other display and interface solutions by providing dedicated high-current regulation. The series targets consumer electronics manufacturers seeking integrated power stages. It fits within the broader category of DC-DC regulators used in mobile and wearable technology sectors.

Replacement Considerations

As the STCF07PNR is marked obsolete, direct substitutes must be sourced from official replacement lists. Verify pinout compatibility and electrical parameters such as output current and voltage range. Ensure the replacement maintains the same buck-boost topology and package type. Consult manufacturer documentation for recommended cross-reference parts.
