The MAX20050–MAX20053 are high-brightness LED (HBLED) drivers for automotive exterior lighting applications.Consisting of a fully synchronous step-down converterwith integrated MOSFETs, the devices are capable ofdriving a series string of LEDs at up to 2A, with a minimumnumber of external components. The MAX20050/MAX20052 utilize internal loop compensation to minimizecomponent count, while the MAX20051/MAX20053/MAX20053D useexternal compensation for full flexibility.The wide 4.5V to 65V input supply range supports extremeautomotive cold crank and load-dump conditions. A low- andhigh-switching frequency option (400kHz or 2.1MHz)provides the designer with the flexibility to optimize forsolution size or efficiency, while avoiding interferencewithin the AM band. Spread spectrum provides furtheroptions for the designer to reduce EMI at the system level.The MAX20050/MAX20051 have an internal switchingfrequency of 400kHz, while the MAX20052/MAX20053have an internal switching frequency of 2.1MHz. In addition,the MAX20051B has spread spectrum disabled.High-side current regulation means only a singleconnection to the LED string is required; grounding of thestring can be done locally. In addition to PWM dimming,the ICs provide analog dimming using the REFI pin. Fullscalecurrent regulation accuracy is ±2.5%, while theaccuracy is ±8% at 10% of full-scale over the full temperaturerange of -40°C to +125°C. A 5V, 10mA LDO output isavailable for biasing other circuits.Fault-protection mechanisms include output overload,short-circuit, and device overtemperature protection. Thedevices are specified for operation over the full -40°C to+125°C temperature range and are available in thermallyenhanced 12-pin (3mm x 3mm) TDFN and 14-pin (5mm x4.4mm) TSSOP packages with an exposed pad.

In eithercase the minimum pulse width is 500ns. Phase-shifteddimming of the strings is incorporated for lower EMI.Comprehensive diagnostic information is also availablevia the I2C interface, while stand-alone operation is also supported.The MAX20444B is available in a 24-pin TQFN or 24-pin side-wettable TQFN (SWTQFN) package and operates over the -40°C to +125°C temperature range.ApplicationsCentral Information DisplaysInfotainment DisplaysInstrument Clusters

The MAX20078 is a high-voltage, synchronous n-channel MOSFET controller for high-current buck LED drivers. The device uses a proprietary average current-mode-control scheme to regulate the inductor current. This control method does not need any control-loop compensation while maintaining nearly constant switching frequency. Inductor current sense is achieved by sensing the current in the bottom synchronous n-channel MOSFET. It does not require any current sense at high voltages. The device operates over a wide 4.5V to 65V input range. The device is designed for high-frequency operation and can operate at switching frequencies as high as 1MHz. The high- and low-side gate drivers have peak source and sink current capability of 2A. The driver block also includes a logic circuit that provides an adaptive nonoverlap time to prevent shoot-through currents during transition. The device includes both analog and PWM dimming. The device includes a 5V VCC regulator capable of delivering 10mA to external circuitry. The device also includes a current monitor that provides an analog voltage proportional to the inductor current. The device has a fault flag that indicates open and shorts across the output. Protection features include inductor current-limit protection, overvoltage protection, and thermal shutdown. The MAX20078 is available in a space-saving (3mm × 3mm), 16-pin TQFN or a 16-pin TSSOP package and is specified to operate over the -40°C to +125°C automotive temperature range.
