LM3532

具有可編程環(huán)境光感應(yīng)功能和 I2C 兼容接口的高效白光 LED 驅(qū)動(dòng)器; ? Drives up to 3 Parallel High-Voltage LED Strings at 40 V Each With up to 90% Efficiency\n? 0.4% Typical Current Matching Between Strings\n? 256 Level Logarithmic and Linear Brightness Control With 14-Bit Equivalent Dimming\n? I2C-Compatible Interface\n? Direct Read Back of Ambient Light Sensor Via 8-bit ADC\n? Programmable Dual Ambient Light Sensor Inputs With Internal Sensor Gain Selection\n? Dual External PWM Inputs for LED Brightness Adjustment\n? Independent Current String Brightness Control\n? Programmable LED Current Ramp Rates\n? 40-V Overvoltage Protection\n? 1-A Typical Current Limit;

The LM3532 is a 500-kHz fixed frequency asynchronous boost converter which provides the power for 3 high-voltage, low-side current sinks. The device is programmable over an I2C-compatible interface and has independent current control for all three channels. The adaptive current regulation method allows for different LED currents in each current sink thus allowing for a wide variety of backlight and keypad applications.The main features of the LM3532 include dual ambient light sensor inputs each with 32 internal voltage setting resistors, 8-bit logarithmic and linear brightness control, dual external PWM brightness control inputs, and up to 1000:1 dimming ratio with programmable fade in and fade out settings.The LM3532 is available in a 16-pin, 0.4-mm pitch thin DSBGA package. The device operates over a 2.7-V to 5.5-V input voltage range and the ?40°C to +85°C temperature range.
