Product Overview
LTC3212 is a low noise charge pump RGB LED driver capable of driving three LEDs upto 25mA each from a 2.7V to 5.5V input. Low external part count (one flying capacitor, two bypass capacitors and one to three programming resistors) makes the device ideally suited for small, battery-powered applications. Built-in soft-start circuitry prevents excessive inrush current during start-up and mode switching. High switching frequency enables the use of small external capacitors. The charge pump shuts down to a high impedance mode to prevent LED leakage while the device is off. Each LED may be individually turned on or off via a single pin interface. The current through the LEDs may be individually programmed with resistors or may share a single programming resistor. White mode adjusts the red, green and blue LED current ratios for a white light when all three LEDs are programmed to be on. It is used in application like cellular phones, media players, RGB back lights.
- Power and current control for driving RGB LEDs
- Individually programmable current sources, CLK frequency is 900KHz typical
- 1x or 2x mode, low noise, constant frequency charge pump
- Single wire enable control for all LEDs
- White mode adjusts R, G, B currents for white light
- 25mA maximum LED current
- Input voltage range is 2.7V to 5.5V
- Automatic soft-start, mode switching and output disconnect in shutdown mode
- IVIN operating current is 0.4mA typical at (ICPO = 0mA, 1x mode)
- Operating temperature is -40°C to 85°C, package style is 12-lead plastic DFN
