STCF03ITBR

Overview

The STCF03ITBR is a high-power white LED driver IC manufactured by STMicroelectronics. It integrates a DC-DC regulator with step-down (buck) and step-up (boost) capabilities, designed for efficient power management in lighting applications. The device supports I2C dimming control and delivers an output current of up to 800mA, specifically optimized for flash operations. Operating at a switching frequency of 1.8MHz, it utilizes a 25-TFBGA (3x3) surface-mount package to ensure compact integration within portable electronic devices.

Feature Summary

• Integrates buck and boost DC-DC regulators for flexible voltage conversion
• Supports I2C interface for precise digital dimming control
• Optimized internal driver architecture for high-performance flash applications

Applications

• Mobile phone camera flash systems
• Portable device illumination modules
