TEXAS INSTRUMENTS LM3697YFQR 发光二极管驱动器, 1输出, 升压逐步上升, 2.7V-5.5V输入, 1MHz开关, 40V/30mA输出, DSBGA-12
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.
