The SC628AULTRT from Semtech is a switched capacitor charge pump LED driver designed specifically for camera flash applications. It integrates internal switches and provides a single output capable of delivering up to 1A flash current. The charge pump topology allows efficient voltage conversion without requiring an inductor.
Key specifications include an I2C interface for precise dimming control, a switching frequency of 250kHz, and an operating temperature range of -40°C to +85°C. The device operates from a minimum supply voltage of 3V and is intended for portable battery-powered devices.
The IC is housed in a compact 20-VFQFN exposed pad package (also known as 20-MLPQ-UT, 3x3mm) for surface mount assembly. The exposed pad aids in thermal dissipation, making it suitable for high-current flash operation.
Compliance information indicates the device is listed as RoHS3 compliant and REACH unaffected. The SC628AULTRT is well-suited for smartphone and other portable camera flash modules where space and efficiency are critical.
