Product Overview
LTC3219 is a highly integrated multidisplay LED driver. This device contains a high efficiency, low noise charge pump to provide power to nine universal LED current sources. This device requires only five small ceramic capacitors to form a complete LED power supply and current controller. The maximum display currents are set by an internal precision current reference. Independent dimming, On/Off, blinking and gradation control for all current sources is achieved via the I²C serial interface. 6-bit linear DACs are available for adjusting brightness levels for each universal LED current source. This device charge pump optimizes efficiency based on the voltage across the LED current sources. The device powers up in 1x mode and will automatically switch to boost mode whenever any enabled LED current source begins to enter dropout. It is used in application such as video phones with QVGA+ displays etc.
- Multimode charge pump provides upto 91% efficiency
- Slew limited switching reduces conducted and radiated noise (EMI)
- Upto 250mA total output current, internal current reference
- Automatic or forced mode switching
- Internal soft-start limits inrush current
- Short-circuit/thermal protection
- VBAT operating voltage range is 2.9V to 5.5V
- IVBAT operating current is 0.4mA typical at (ICPO = 0, 1x mode)
- Operating temperature is -40°C to 85°C
- Package style is 20-lead plastic QFN
