FFF CompatibilityThe LP5523 uses a 25-pin DSBGA footprint which is completely incompatible with the 16-bump WLCSP pattern of the target.It is a chip-scale package (DSBGA) utilizing a similar 0.4 mm pitch, though its physical envelope (2.26 mm x 2.26 mm) is slightly larger than the target (1.61 mm x 1.61 mm).It provides 9 output channels instead of 6, but has a lower maximum full-scale output current per channel (25.5 mA vs 30 mA on the FAN5702).The CAT3626 is in a larger 16-TQFN (4x4 mm) footprint, which is pin-incompatible and completely different from the target's tiny 16-bump WLCSP footprint.It is a leadless QFN package with physical dimensions of 4 mm x 4 mm, whereas the target is a WLCSP package of 1.61 mm x 1.61 mm.It performs the same electrical job as a 1x/1.5x fractional charge-pump-based 6-channel LED driver controlled via an I2C interface.
AI Summary

FAN5702UC20X by onsemi: LED Driver IC 6 Output DC DC Regulator Switched Capacitor (Charge Pump) I2C, PWM Dimming 30mA 16-WLCSP (1.71x1.71).

This is an active, highly integrated 9-channel LED driver with I2C control in a compact DSBGA-25 package. It is an excellent alternative if you need to keep a chip-scale layout, although it has a lower max current per channel. It also features autonomous pattern engines that can offload backlight animation tasks from the host processor.

  • Extremely compact micro-SMD (DSBGA-25) package with 0.4 mm pitch
  • Offers 9 independent LED channels instead of 6
  • Active status with excellent documentation and support from Texas Instruments
  • Lower maximum LED current per channel (25.5 mA vs 30 mA)
  • Requires a complete PCB footprint redesign to accommodate 25-pin DSBGA package

This is an active 6-channel charge pump LED driver from the same manufacturer (onsemi) that offers a compatible functional replacement. It supports I2C-controlled dimming up to 32 mA per channel and operates from a similar supply range. However, it requires a board redesign as it comes in a much larger TQFN-16 (4x4 mm) package rather than a tiny WLCSP.

  • Direct functional equivalent with 6 channels
  • Features I2C interface for programmable dimming control
  • Active lifecycle status from onsemi
  • Requires board layout redesign due to larger package size
  • Minimum supply voltage is 3.0V compared to 2.7V on the FAN5702

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
