It supports flyback, SEPIC, buck, and boost topologies, operates from 4.5 V to 36 V, and includes internal switches. ## Dimming and switching frequency: what they mean for the BOM Dimming is handled via I²C or PWM, selectable per application. PWM dimming is the standard for high-contrast backlight control in automotive infotainment and cluster displays; I²C dimming simplifies the wiring harness when the host microcontroller is already on the bus. The switching frequency is programmable from 400 kHz to 2.2 MHz. A higher frequency shrinks the inductor and output capacitor, saving board area, but pushes switching losses—the 2.2 MHz ceiling is useful for compact designs where EMI filtering is managed with a shielded inductor. At the low end, 400 kHz improves efficiency for higher step-up ratios or when thermal constraints dominate. ## Temperature grade and package for automotive deployment Rated for -40°C to +125°C ambient. The 24-SWTQFN (4x4 mm) package with wettable flanks supports AOI of solder joints. ## Lifecycle and sourcing posture The MAX20444CATG/VY+ is listed as Active with ROHS3 compliance.","metaTitle":"MAX20444CATG/VY+ DC-DC Controller, Automotive Backlight","metaDescription":"MAX20444CATG/VY+ DC-DC controller for automotive backlight. 4.5V-36V input, 4 outputs, I²C/PWM dimming, 400kHz-2.2MHz, -40°C to +125°C.
