Application Scenarios & Design Considerations

White LED 1x/1.5x Charge Pump in UCSP and Thin QFN

Alternative Part Number

  • TPS61160DRVR --: Single-channel WLED boost driver in small DFN package, similar boost topology and constant-current LED drive, good drop-in functional alternative.
  • AP3031KTR-G1 --: White LED boost converter with internal switch and PWM dimming, comparable input range and output current capability.
  • LT1937ES5#TRPBF --: Step-up white LED driver in SOT-23, similar boost LED driver function with dimming control, widely available alternative.
  • LM3532TMX/NOPB --: I2C-controlled LED backlight driver with multiple current sinks, suitable replacement for display backlight applications using the MAX1573.
  • CAT3649HV4-T2 --: Quad-mode charge pump LED driver with similar output current capability and small package, offering a close functional match.
