Add To BomLM3697YFQR General Description
The LM3697 11-bit LED driver provides high-performance backlight dimming for 1, 2, or 3 series LED strings while delivering up to 90% efficiency. The boost converter with integrated 1-A, 40-V MOSFET automatically adjusts to LED forward voltage to minimize headroom voltage and effectively improve LED efficiency.
The LM3697 is a high-efficiency three-string power source for backlight or keypad LEDs in smart-phone handsets. The high-voltage inductive boost converter provides the power for three-series LED strings for display backlight and keypad functions (HVLED1, HVLED2, and HVLED3).
An additional feature is a pulse width modulation (PWM) control input for content adjustable backlight control, which can be used to control any high-voltage current sink.
The LM3697 is fully configurable via an I2C-compatible interface. The device operates over a
2.7-V to 5.5-V input voltage range and a −40°C to +85°C temperature range.
Features
- Drives three parallel high-voltage led strings for display and keypad lighting
- High-voltage strings capable of up to 40-V output voltage and up to 90% efficiency
- Up to 30 mA per current sink
- 11-Bit configurable dimming resolution
- PWM input for content adjustable brightness control (CABC)
- Fully configurable LED grouping and control
- Integrated 1-A/40-V MOSFET
- Adaptive boost output to LED voltages
- Selectable 500-kHz and 1-MHz switching frequency
- Four configurable overvoltage protection thresholds (16 V, 24 V, 32 V, and 40 V)
- Overcurrent protection
- Thermal shutdown protection
- 29-mm2 Total solution size
