| NPA Number 001 Announcement New Product AP3154A/56 Small LCD screen backlighting charge pump LED drivers Description TheAP3154AandAP3156 arechargepumpLEDdrivers forsmallLCDscreen backlighting.Theyarewell suitedforLCDscreensless than3". Both useatrimodecharge pumpswitch(1X),fractional (1.5X),anddoubling(2X) conversiontomaximize efficiencyinwhiteLED applications. Alowexternalpartscount (two1Fflyingandtwo small1FcapacitorsatVIN andVOUT)makethemideally suitedforsmall,battery poweredapplications. Aserialdigitalinterfaceis usedtoenable,disableand setcurrentforeachLEDwith a32levellogarithmicscale plusfourlowcurrent settingsdownto50Afor i d f optimizedefficiency.. The Diodes advantage The AP3154A and AP3156 provide a simple cost effective solution for small screen LCD backlighting x1/x1.5/x2 tri-mode voltage conversion Increases efficiency giving longer battery life. No inductor, diodes inductor Reduces EMI and reduces PCB area SDI digital interface Versatile control to program LED current with 16-level/32-level logarithmic scale Small footprint low profile packages Reduces PCB area and height restrictions Soft-start & Soft-stop p Reduces In-rush current during start up and power down.
