AP3154A

NPA Number 001 Announcement New Product AP3154A/56 Small LCD screen backlighting charge pump LED drivers Description The AP3154A and AP3156  are charge pump LED drivers  for small LCD screen  backlighting. They are well  suited for LCD screens less  than 3”. Both use a tri‐mode charge  pump switch (1X), fractional (1.5X), and doubling (2X)  conversion to maximize  efficiency in white LED  applications. A low external parts count  (two 1μF flying and two  small 1μF capacitors at VIN and VOUT) make them ideally  suited for small, battery‐ powered applications. A serial digital interface is  used to enable, disable and  set current for each LED with  a 32‐level logarithmic scale  plus four low‐current  settings down to 50μA for  optimized efficiency.. 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 diodes 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 Reduces In-rush current during start up and power down.
