The MAX25206/MAX25207/MAX25208 are automotive 2.2MHz synchronous step-down controllers with 7µA IQ. These devices operate with an input voltage supply from 3.5V to 60V (MAX25206/MAX25207) and 70V (MAX25208). They can operate in dropout condition by running at 99% (typ) duty cycle. These controllers are intended for applications with mid- to high-power requirements that operate at a wide input voltage range such as during automotive cold-crank or engine stop-start conditions. The MAX25207 has an optional bypass mode which allows 100% high-side switch on until step-down function is needed during automotive transients.The MAX25206/MAX25207/MAX25208 step-down controllers operate at up to 2.2MHz frequency to allow small external components, reduced output ripple, and to guarantee no AM band interference. The switching frequency is resistor adjustable (220kHz to 2200kHz). SYNC input programmability enables three frequency modes for optimized performance: forced fixed-frequency operation (FPWM), skip mode with ultra-low quiescent current, and synchronization to an external clock. The IC also provides SYNCOUT output to enable two controllers to operate in parallel. The MAX25206/MAX25207/MAX25208 have a pin selectable spread-spectrum option for frequency modulation to minimize EMI.The MAX25206/MAX25207/MAX25208 feature a PGOOD monitor and undervoltage lockout. Protection features include cycle-by-cycle current limit and thermal shutdown. These controllers are specified for operation over the -40°C to +125°C automotive temperature range.Applications24V Truck systems, Infotainment Systems, 48V systems

The MAX25220/MAX25221/MAX25221B/MAX25221C are a 4-channel TFT-LCD power IC that provides symmetrical positive AVDD and negative NAVDD supplies as well as VGONand VGOFFgate supplies. In addition, a VCOM buffer with output voltage range above and below ground and a temperature measurement block are integrated (MAX25221/B/C).The device contains non-volatile memory so that the values of all outputs can be calibrated for the lifetime of the device (maximum five times).Programming is carried out using the built-in I2C interface, which can also be used to read back diagnostic information. A stand-alone mode is also available.The temperature sensor interface block measures the temperature optionally allowing the VCOM output voltage to be adjusted depending on the measured temperature.The MAX25220/MAX25221/MAX25221B/MAX25221C are available in a TQFN package and operates in the -40°C to +125°C temperature range.ApplicationsCentral Information DisplaysInfotainment DisplaysInstrument Clusters
