It runs a boost or SEPIC topology with six outputs at 120 mA each and a 52 V output ceiling. ## Dimming and control — three ways to set brightness Dimming comes three ways: analog voltage, I²C register writes, or a direct PWM input. That covers the range from a simple pot-adjust backlight on a retrofit cluster to a CAN-bridged I²C command from the body controller. The switching frequency sweeps from 400 kHz to 2.2 MHz, so you can trade inductor size against switching loss depending on the board real estate available. ## Temperature grade and environment Rated for -40°C to 125°C, this part is qualified for under-hood and cabin automotive environments. The 24-TQFN (4x4 mm) package is a surface-mount footprint that fits tight multilayer boards typical of modern head units and display modules. ## Sourcing and lifecycle The MAX20446ATG/V+ carries an active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX20446ATG/V+ LED Driver Controller, 6-Ch, Boost/SEPIC","metaDescription":"Maxim MAX20446ATG/V+ DC-DC controller for automotive displays. 6 outputs, 120mA/ch, analog/I²C/PWM dimming, -40°C to 125°C, 24-TQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"DC DC Controller","Dimming":"Analog, I²C, PWM","Package":"Tube","Topology":"Boost, SEPIC","Frequency":"400kHz ~ 2.2MHz","Applications":"Central Information Displays, Infotainment Displays, Instrument Clusters","Mounting Type":"Surface Mount","lifecycle_stage":"eol_hot","Voltage - Output":"52V","Number of Outputs":"6","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 125°C","Voltage - Supply (Max)":"40V","Voltage - Supply (Min)":"4.5V","Supplier Device Package":"24-TQFN (4x4)","Current - Output / Channel":"120mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.39","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.39000","currency":"USD"},{"qty":10,"price":"$6.08300","currency":"USD"},{"qty":100,"price":"$5.02670","currency":"USD"},{"qty":500,"price":"$4.40234","currency":"USD"},{"qty":1000,"price":"$4.16221","currency":"USD"},{"qty":2000,"price":"$4.06616","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX20446.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the dimming interface of MAX20446ATG/V+?","answer":"The MAX20446ATG/V+ supports analog dimming, I²C dimming, and PWM dimming.
