Quality Control: Learn More
The Microchip Technology MIC2291BD5-TR is a highly efficient, single-output DC-DC boost LED driver IC. Designed for high-current LED driving, this device features an internal 1.2A switch and operates at a fixed 1.2MHz switching frequency, enabling compact external component selection. It supports both analog and PWM dimming for precise brightness control, making it suitable for applications requiring sophisticated illumination management.
The MIC2291BD5-TR is engineered for robust performance across a wide temperature range of -40°C to 125°C. Its 2.5V to 10V input voltage range and TSOT-23-5 package are ideal for space-constrained designs. Common applications include camera flash modules and other portable electronic devices where efficient and controllable LED illumination is critical. This component is supplied in tape and reel packaging for automated assembly.
