It drives four LED channels at 28 mA each, with PWM dimming. ## Key ratings and what they mean for the BOM Four outputs at 28 mA per channel is the headline rating — enough for a small backlight string or indicator array. The charge pump topology means no external inductor, which saves board area and BOM cost compared to a boost converter, but efficiency is lower at high input-to-output voltage ratios. PWM dimming allows linear brightness control without colour shift, critical for display backlights. The 1 MHz switching frequency pushes ripple into a band where small ceramic capacitors are effective, but layout must keep the switching loop tight to avoid radiated emissions. ## Lifecycle and sourcing reality The MAX1573ETE+ carries an Active lifecycle status with ROHS3 compliance. No official replacement has been announced; the part is still the recommended buy for new backlight designs requiring a 4-channel charge-pump driver.","metaTitle":"MAX1573ETE+ LED Driver, DC-DC Regulator, 4-Ch 28mA, 16-TQFN","metaDescription":"MAX1573ETE+ is an active LED driver IC from Maxim Integrated.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"DC DC Regulator","Dimming":"PWM","Package":"Tube","Topology":"Switched Capacitor (Charge Pump)","Frequency":"1MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"16-WQFN Exposed Pad","lifecycle_stage":"eol_hot","Number of Outputs":"4","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.7V","Supplier Device Package":"16-TQFN (4x4)","Current - Output / Channel":"28mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.43","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.43000","currency":"USD"},{"qty":10,"price":"$4.88000","currency":"USD"},{"qty":25,"price":"$4.61320","currency":"USD"},{"qty":100,"price":"$3.99810","currency":"USD"},{"qty":250,"price":"$3.79304","currency":"USD"},{"qty":500,"price":"$3.40350","currency":"USD"},{"qty":1000,"price":"$2.87042","currency":"USD"},{"qty":2500,"price":"$2.72690","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1573.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum output current of MAX1573ETE+?","answer":"Each of the four outputs delivers up to 28 mA.
