It supports boost and buck-boost LED driver topologies with a wide input voltage range of 4.5 V to 65 V, making it suitable for automotive battery-powered lighting systems. The device incorporates a rail-to-rail current sense amplifier for precise LED current measurement with better than +\/-4% accuracy across the full junction temperature range of -40\u00b0C to 150\u00b0C. Spread spectrum frequency modulation reduces EMI, simplifying filter design. The controller offers dual dimming capability: analog dimming via the IADJ input with over 15:1 contrast ratio, and PWM dimming through the DIM\/PWM pin with over 1000:1 range. An internal PWM generator converts a DC voltage at the DIM\/PWM pin to a corresponding duty cycle, enabling standalone dimming without an external PWM source.","working_principle":"The TPS92692QPWPRQ1 operates through five key subsystems: (1) The oscillator and spread spectrum block generates the switching frequency (adjustable 80-800 kHz) with frequency dithering to spread EMI energy and reduce peak emissions. (2) The peak current-mode control loop uses a transconductance error amplifier and current sense comparator to regulate the LED current. The COMP pin allows external compensation for loop stability. (3) The dimming subsystem supports two modes: analog dimming via the IADJ pin which scales the current reference, and PWM dimming via the DIM\/PWM pin which chops the LED current at the desired duty cycle. The internal PWM generator creates a PWM signal from a DC voltage. (4) The PDRV gate driver output controls an external P-channel series MOSFET for fast LED current on\/off during PWM dimming, improving dimming linearity at low duty cycles. (5) The protection and monitoring block includes output overvoltage protection, output short-circuit protection with hiccup mode, thermal shutdown, and a current monitor (IMON) output with fault flag (FLT) indicator.","pin_description":"<table><tr><td>Pin No.<\/td><td>Pin Name<\/td><td>Function<\/td><\/tr><tr><td>1<\/td><td>VIN<\/td><td>Input supply voltage<\/td><\/tr><tr><td>2<\/td><td>VREF<\/td><td>Internal reference voltage output<\/td><\/tr><tr><td>3<\/td><td>IADJ<\/td><td>Analog LED current adjust input<\/td><\/tr><tr><td>4<\/td><td>SS<\/td><td>Soft-start capacitor connection<\/td><\/tr><tr><td>5<\/td><td>DM<\/td><td>Dither modulation frequency set resistor<\/td><\/tr><tr><td>6<\/td><td>RT<\/td><td>Switching frequency set resistor<\/td><\/tr><tr><td>7<\/td><td>DIM\/PWM<\/td><td>PWM dimming input \/ internal PWM generator<\/td><\/tr><tr><td>8<\/td><td>COMP<\/td><td>Error amplifier output for compensation<\/td><\/tr><tr><td>9<\/td><td>IS<\/td><td>Current sense amplifier inverting input<\/td><\/tr><tr><td>10<\/td><td>PDRV<\/td><td>P-channel MOSFET gate driver output<\/td><\/tr><tr><td>11<\/td><td>RAMP<\/td><td>Slope compensation capacitor<\/td><\/tr><tr><td>12<\/td><td>GATE<\/td><td>Main N-channel MOSFET gate driver output<\/td><\/tr><tr><td>13<\/td><td>CSN<\/td><td>Current sense negative input (switch current)<\/td><\/tr><tr><td>14<\/td><td>CSP<\/td><td>Current sense positive input (LED current)<\/td><\/tr><tr><td>15<\/td><td>OV<\/td><td>Output overvoltage protection input<\/td><\/tr><tr><td>16<\/td><td>SLOPE<\/td><td>Slope compensation resistor<\/td><\/tr><tr><td>17<\/td><td>GND<\/td><td>Device ground<\/td><\/tr><tr><td>18<\/td><td>IMON<\/td><td>Current monitor output<\/td><\/tr><tr><td>19<\/td><td>FLT<\/td><td>Fault flag output (open drain)<\/td><\/tr><tr><td>20-21<\/td><td>NC\/PAD<\/td><td>Not connected \/ Thermal pad<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Automotive front lighting (LED headlights, DRL) requiring AEC-Q100 Grade 1 qualification with analog and PWM dimming<\/li><li>Driver monitoring system (DMS) infrared LED drivers needing precise current control over wide temperature range<\/li><li>Industrial LED lighting with buck-boost topology for battery-powered applications from 12 V to 48 V<\/li><li>Emergency vehicle lighting systems requiring spread spectrum for EMI compliance in RF-sensitive environments<\/li><\/ul>","alternative_models":"<table><tr><td>Model<\/td><td>Brand<\/td><td>Vin Range<\/td><td>Dimming<\/td><td>Qualification<\/td><\/tr><tr><td>TPS92692PWPR<\/td><td>TI<\/td><td>4.5-65 V<\/td><td>Analog + PWM<\/td><td>Catalog<\/td><\/tr><tr><td>LM3492QMH<\/td><td>TI<\/td><td>6-65 V<\/td><td>PWM<\/td><td>AEC-Q100<\/td><\/tr><tr><td>AL8862Q<\/td><td>Diodes Inc<\/td><td>4.5-40 V<\/td><td>PWM\/Analog<\/td><td>AEC-Q100<\/td><\/tr><tr><td>BD18347EFV-M<\/td><td>Rohm<\/td><td>4.5-36 V<\/td><td>PWM<\/td><td>AEC-Q100<\/td><\/tr><tr><td>MAX20078ATC\/VY+<\/td><td>ADI<\/td><td>5-65 V<\/td><td>Analog + PWM<\/td><td>AEC-Q100<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3190","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=3190"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3190\/revisions"}],"predecessor-version":[{"id":3271,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3190\/revisions\/3271"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=3190"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=3190"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=3190"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=3190"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
