A high-efficiency charge pump enables LED driving over full Li-ion battery voltage range. The device is equipped with an internal program memory, which allows operation without processor control. It has an I²C-compatible control interface with four pin-selectable addresses. The INT pin can be used to notify processor when a lighting sequence has ended (interrupt function). Also, the device has a trigger input interface, which allows synchronization, for example, between multiple LP55231 devices. Excellent efficiency is maintained over a wide operating range by autonomously selecting the best charge pump gain based on LED forward voltage requirements. The device is able to automatically enter power-save mode when LED outputs are not active, thus lowering idle current consumption down to 10µA (typical). \u003cul\u003e \u003cli\u003eAdaptive high-efficiency 1x\/1.5x fractional charge pump - efficiency up to 94%\u003c\/li\u003e \u003cli\u003eLED drive efficiency up to 93%\u003c\/li\u003e \u003cli\u003eCharge pump with soft-start\u003c\/li\u003e \u003cli\u003eOvercurrent and short-circuit protection\u003c\/li\u003e \u003cli\u003eBuilt-in LED test\u003c\/li\u003e \u003cli\u003eTwo-wire I²C-compatible control interface\u003c\/li\u003e \u003cli\u003eFlexible instruction set\u003c\/li\u003e \u003cli\u003eLarge SRAM program memory\u003c\/li\u003e \u003cli\u003eSmall application circuit\u003c\/li\u003e \u003cli\u003eSource (high-side) drivers\u003c\/li\u003e \u003cli\u003eArchitecture supports colour control\u003c\/li\u003e \u003cli\u003e200nA Typical standby current\u003c\/li\u003e \u003cli\u003e10µA (IVDD) Typical automatic power save mode\u003c\/li\u003e \u003cli\u003eGreen product and no Sb\/Br\u003c\/li\u003e \u003c\/ul\u003e Applications \u003cp\u003eLED Lighting\u003c\/p\u003e\u003ch4\u003eProduct details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDevice Topology\u003c\/td\u003e\n\u003ctd\u003eCharge Pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Min\u003c\/td\u003e\n\u003ctd\u003e2.7V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Max\u003c\/td\u003e\n\u003ctd\u003e5.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage Max\u003c\/td\u003e\n\u003ctd\u003e5.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current Max\u003c\/td\u003e\n\u003ctd\u003e25.5mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitching Frequency\u003c\/td\u003e\n\u003ctd\u003e1.25MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo. of Outputs\u003c\/td\u003e\n\u003ctd\u003e9Outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIC Mounting\u003c\/td\u003e\n\u003ctd\u003eSurface Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDriver Case Style\u003c\/td\u003e\n\u003ctd\u003eWQFN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo. of Pins\u003c\/td\u003e\n\u003ctd\u003e24Pins\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature Min\u003c\/td\u003e\n\u003ctd\u003e-40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature Max\u003c\/td\u003e\n\u003ctd\u003e85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Range\u003c\/td\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutomotive Qualification Standard\u003c\/td\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMSL\u003c\/td\u003e\n\u003ctd\u003eMSL 1 - Unlimited\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch4\u003eOther details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTEXAS INSTRUMENTS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e LP55231SQE\/NOPB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eEach (Supplied on Cut Tape)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Change Notice EN\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"https:\/\/www.farnell.com\/datasheets\/2859225.pdf\" target=\"_blank\" title=\"Download data sheet Texas Instruments LP55231SQE\/NOPB \u0026lt;b\u0026gt;LP55231SQE\/NOPB\u0026lt;\/b\u0026gt; Led Driver 9 Outputs Charge Pump 2.7V-5.5V in 1.25MHz Switch 5.5V\/25.5mA out WQFN-24\" download\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/files\/file_4379f50c-e237-48f9-beae-a4e625c5b304_icon.png?9736775303194905289\" alt=\"Download technical document - datasheet - Tanotis India\" width=\"25\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"color: #999999;\"\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
