MAX20078EVKIT#
Analog Devices Inc.
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.

MAX20090BATP/V+T
Analog Devices Inc.
The MAX20090 is a single-channel high-brightness LED (HB LED) driver for automotive front-light applications such as high beam, low beam, daytime running lights (DRLs), turn indicators, fog lights, and other LED lights. It can take an input voltage from 5V to 65V and drive a string of LEDs with a maximum output voltage of 65V. The device senses output current at the high side of the LED string. High-side current sensing is required to protect for shorts from the output to the ground or battery input. It is also the most flexible scheme for driving LEDs, allowing boost, high-side buck, SEPIC mode, or buck-boost-mode configurations. The PWM input provides LED dimming ratios of up to 1000:1, and the ICTRL input provides additional analog dimming capability in the controller. The device also includes a fault flag ( active-low FLT) that indicates open string, shorted string, and thermal shutdown. The device has built-in spread-spectrum modulation for improved electromagnetic-compatibility performance. The device can also be used in zeta and Cuk converter configurations, if necessary in some applications. The MAX20090 is available in a space-saving (4mm × 4mm), 20-pin TQFN, 20-pin side-wettable TQFN, or a 20-pin TSSOP package and is specified to operate over the -40°C to +125°C automotive temperature range.
