PWM dimming on the control input lets a host processor or application processor set the LED brightness by modulating the duty cycle, avoiding the colour shift that analog current dimming can cause. ## Switching frequency and external component sizing The LP5520TL/NOPB operates at two internal oscillator frequencies — 1.22 kHz and 19.52 kHz — which set the switching rate of the boost converter. The lower frequency favours efficiency at light loads; the higher frequency shrinks the inductor and output capacitor values at the cost of slightly higher switching losses. Because the part integrates the switching transistor (internal switch = yes), the external BOM stays compact: an inductor, a Schottky diode, and a few ceramic capacitors are all that is needed to complete the boost stage. ## 25-bump uSMD — board-level integration Housed in a 25-bump wafer-level chip-scale package (25-WFBGA, also designated 25-uSMD), the LP5520TL/NOPB occupies roughly the footprint of the silicon die itself — no mould compound overhang. The 0.50 mm ball pitch demands a PCB with fine trace/space capability and a solder-mask-defined pad layout. Surface-mount assembly with a standard lead-free reflow profile works, but the uSMD package is moisture-sensitive — the floor life rating (MSL) should be verified from the TI packaging label before the reel is opened. ## Temperature grade and operating environment Rated for -30°C to +85°C ambient, the LP5520TL/NOPB covers the industrial temperature band — suitable for outdoor-rated displays, automotive cabin backlighting (not engine-bay), and portable equipment that sees freezing storage.","metaTitle":"Texas Instruments LP5520TL/NOPB LED Driver, 3-Ch, 60mA","metaDescription":"Active-production step-up (boost) LED driver from Texas Instruments. 3 outputs, 60 mA per channel, PWM dimming, 5-20V output range. 25-bump uSMD package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"DC DC Regulator","Dimming":"PWM","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"1.22kHz, 19.52kHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"25-WFBGA","lifecycle_stage":"eol_hot","Voltage - Output":"5V ~ 20V","Number of Outputs":"3","Internal Switch(s)":"Yes","Operating Temperature":"-30°C ~ 85°C (TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.9V","Supplier Device Package":"25-uSMD","Current - Output / Channel":"60mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.38","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.38000","currency":"USD"},{"qty":10,"price":"$4.83400","currency":"USD"},{"qty":25,"price":"$4.56960","currency":"USD"},{"qty":100,"price":"$3.96040","currency":"USD"},{"qty":250,"price":"$3.75728","currency":"USD"},{"qty":500,"price":"$3.37140","currency":"USD"},{"qty":1250,"price":"$2.87400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5777d2dca10c978898133e56de21fc98.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the LP5520TL/NOPB used for?","answer":"The LP5520TL/NOPB is a step-up (boost) DC-DC regulator designed specifically for LED backlight applications. Its three 60 mA outputs with PWM dimming make it a fit for driving multi-string LCD backlights in portable devices, handheld instruments, and small-panel displays."},{"question":"How does the LP5520TL/NOPB compare to the LP8550TLE/NOPB?","answer":"Both are step-up boost LED drivers with PWM dimming, internal switches, and the same supply voltage range. The LP5520TL/NOPB drives three outputs at 60 mA each, while the LP8550TLE/NOPB drives six outputs at 50 mA each. The LP8550TLE/NOPB therefore supports more LED strings but at a slightly lower per-channel current. The packages differ — the LP5520TL/NOPB comes in a 25-bump uSMD, while the LP8550TLE/NOPB uses a different footprint — so they are not drop-in replacements without a board layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP5520TL-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP5520TL-NOPB when reusing this data.
