MAX16816 - NEW! - Programmable Switch-Mode LED Driver With Analog-Controlled PWM Dimming

The MAX16816 is a current-mode, high-brightness LED (HB LED) driver designed to control two external N-Channel MOSFETs for single-string LED current regulation. The MAX16816 integrates all the building blocks necessary to implement fixed-frequency HB LED Drivers with wide-range dimming control and EEPROM-programmable LED current binning with a factor of up to 1.6. This device is configurable to operate as a stepdown (buck), Step-up (boost), or Step-up Step-down (buck-boost) current Regulator
Current-mode control with adjustable leading-edge blanking simplifies control-loop design. Adjustable slope compensation stabilizes the current loop when operating at duty cycles above 50%. The MAX16816 operates over a wide input voltage range and is capable of withstanding automotive load-dump events. Multiple MAX16816 devices CAN be synchronized to each other or to an external Clock The MAX16816 includes a floating dimming driver for brightness control with an external N-Channel MOSFET in series with the LED string.
HB LEDs using the MAX16816 CAN achieve efficiencies of over 90% in automotive applications. The MAX16816 also includes a 1.4A source and 2A sink Gate driver for driving switching MOSFETs in high-power LED Driver applications, such as front light assemblies. Dimming control allows for wide PWM dimming range at frequencies up to 5kHz. Higher dimming ratios (up to 1000:1) are achievable at lower dimming frequencies.
The MAX16816 provides user-programmable features through on-chip nonvolatile EEPROM Registers Ad 63d justable features include a programmable soft-start, LED current (binning), external MOSFET Gate driver supply voltage, slope compensation, leading-edge blanking time, and disabling/enabling of the RT Oscillator
The MAX16816 is available in a 32-pin TQFN package with exposed pad and operates over the -40C to +125C automotive temperature range.
