Best Alternatives to MT9284-28J

Package: SOT-23-6AeroPMIC - LED DriversTopology: BoostSwitching Frequency: 1.2 MHzMax Output Voltage: 28 VFeedback Voltage: 104 mVOperating Input Voltage: 2.5 V to 5.5 V

MT9284-28J replacement options should be treated as boost WLED driver candidates, not confirmed drop-ins. Pinout and feedback voltage are the main checks.

AI replacement insight

Electrical riskhigh

FB voltage differs on all candidates.

Package risklow

Kept candidates are SOT-23-6.

Firmware riskmedium

Dimming or enable behavior may differ.

Sourcing riskmedium

All are catalog matched but not verified.

Can it be replaced directly?

No pin-compatible replacement is confirmed from the provided fields.

Best replacement path

Start with FP6755S6CTR or AP3019AKTR-G1, then verify pinout, FB resistor, OVP, and LED string current.

Main risk

Feedback voltage and pinout are not proven compatible.
