The LTC3210-1 is a low noise charge pump DC/DC converter designed to drive four MAIN LEDs and one high current CAM LED for camera lighting. The LTC3210-1 requires only four small ceramic capacitors and two current set resistors to form a complete LED power supply and current controller.
Built-in soft-start circuitry prevents excessive inrush current during start-up and mode changes. High switching frequency enables the use of small external capacitors. Independent MAIN and CAM full-scale current settings are programmed by two external resistors.
Shutdown mode and current output levels are selected via two logic inputs. ENM and ENC are toggled to adjust the LED currents via internal counters and DACs. A 6-bit linear DAC (64 steps) provides high resolution brightness control for the MAIN display.
The charge pump optimizes efficiency based on the voltage across the LED current sources. The part powers up in 1x mode and will automatically switch to boost mode whenever any enabled LED current source begins to enter dropout. The LTC3210-1 is available in a 3mm × 3mm × 0.75mm 16-lead QFN package.
