The MAX16803 current regulator operates from a 6.5V to 40V input-voltage range and delivers up to a total of 350mA to one or more strings of high-brightness LEDs (HB LEDs). The output current of the MAX16803 is adjusted by using an external current-sense resistor in series with the LEDs. A dimming input allows widerange 'pulsed' PWM operation. Wave-shaping circuitry reduces EMI. The differential current-sense input increases noise immunity. The MAX16803 is well suited for applications requiring high-voltage input and is able to withstand automotive load-dump events up to 40V. An on-board pass element minimizes external components while providing ±3.5% output-current accuracy. Additional features include a 5V regulated output and short-circuit and thermal protection.The MAX16803 is available in a thermally enhanced, 5mm x 5mm, 16-pin TQFN package and is specified over the automotive -40°C to +125°C temperature range.The MAX16836 is a newer and more cost effective product; except for different PWM dimming current slew rates, it provides the same performance and is pin-to-pin compatible with the MAX16803.ApplicationsAutomotive Exterior: Rear Combination Lights (RCL)Automotive Interior: Map, Courtesy, and Cluster LightingEmergency Vehicle Warning LightsGeneral LightingNavigation and Marine IndicatorsSignage, Gasoline Canopies, Beacons

The MAX16818 pulse-width modulation (PWM) LED driver controller provides high-output-current capability in a compact package with a minimum number of external components. The MAX16818 is suitable for use in synchronous and nonsynchronous step-down (buck) topologies, as well as in boost, buck-boost, SEPIC, and Cuk LED drivers. The MAX16818 is the first LED driver controller that enables Maxim's technology for fast LED current transients of up to 20A/µs and 30kHz dimming frequency.This device utilizes average-current-mode control that enables optimal use of MOSFETs with optimal charge and on-resistance characteristics. This results in the minimized need for external heatsinking even when delivering up to 30A of LED current. True differential sensing enables accurate control of the LED current. A wide dimming range is easily implemented to accommodate an external PWM signal. An internal regulator enables operation over a wide input voltage range: 4.75V to 5.5V or 7V to 28V and above with a simple external biasing device. The wide switching frequency range, up to 1.5MHz, allows for the use of small inductors and capacitors.The MAX16818 features a clock output with 180° phase delay to control a second out-of-phase LED driver to reduce input and output filter capacitors size or to minimize ripple currents. The MAX16818 offers programmable hiccup, overvoltage, and overtemperature protection.The MAX16818ETE+ is rated for the extended temperature range (-40°C to +85°C) and the MAX16818ATE+ is rated for the automotive temperature range (-40°C to +125°C). This LED driver controller is available in a lead-free, 0.8mm high, 5mm x 5mm 28-pin TQFN package with an exposed pad.ApplicationsFront Projectors/Rear Projection TVsLCD TVs and Display BacklightPortable and Pocket Projectors

The MAX6966/MAX6967 serial-interfaced peripheralsprovide microprocessors with 10 I/O ports rated to 7V.Each port can be individually configured as either: A 20mA constant-current LED driver (static or pulsewidthmodulated (PWM)). A 10mA constant-current LED driver (static or PWM). An open-drain logic output. An overvoltage-protected Schmitt logic input.Analog and switching LED intensity control is built in: Individual 8-bit PWM control per output. Individual 1-bit analog control (half/full) per output. Global 3-bit analog control applies to all LED outputs.PWM timing of the 10 port outputs may be optionallystaggered, consecutively phased in 45° increments.This spreads the PWM load currents over time in eightsteps, helping to even out the power-supply currentand reduce the RMS current.The MAX6966/MAX6967 can be configured to awakefrom shutdown on receipt of a minimum 3ms pulse onthe active-low CS input. This hardware-wakeup feature allows apower-management controller or similar ASIC to enablethe MAX6966/MAX6967 with preconfigured LED intensitysettings.Shutdown can be programmed to wait up to 4s, fadedown the sink currents to zero for a period of 1/16s to4s, and then shut down. A similar ramp-up from shutdowncan be programmed for 1/16s to 4s.The MAX6966/MAX6967 support hot insertion. All portpins remain high impedance in power-down (V+ = 0V)with up to 8V asserted on them.The DOUT/OSC pin can be configured as either theserial interface data output or optional PWM clockinput. The MAX6966 powers up defaulting as DOUToutput. The MAX6967 defaults as OSC input.For a similar part without the constant-current controls,refer to the MAX7317 data sheet.ApplicationsCell PhonesKeypad BacklightsLCD BacklightsLED Status IndicationPortable EquipmentRGB LED Drivers
