The integrated current outputs can sink up to 130mA LEDcurrent each. The device accepts a wide 4.5V to 36V input voltage range andwithstands direct automotive load-dump events.The internal current-mode switching DC-DC controller supports boost or SEPICtopologies and operates in the 400kHz to 2.2MHz frequency range. Integratedspread spectrum helps reduce EMI. An adaptive output voltagecontrol schememinimizes power dissipation in the LED current-sink paths.The device features I2C-controlled pulse-width-modulation (PWM) dimming andhybrid dimming. In either case, the minimum pulse width is 500ns. Phase-shifteddimming of the strings is incorporated for lower EMI. Comprehensive diagnosticinformation is also available through the I2C interface, while stand-aloneoperation is also supported.The MAX20444C 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.
