SOT-23-6 Package — Extremely compact, ideal for slim charger designs

Typical Applications

Mobile phone and tablet charger repair/design
USB wall adapter power supply
LED driver SMPS (5W–15W range)
Standby power supply for consumer electronics
Low-power AC-DC flyback converter modules

FAQ

Q: What’s the difference between OB2263MP and OB2263AMP?
A: OB2263AMP has improved OVP threshold accuracy. Both are pin-compatible and interchangeable in most designs.

Q: Can OB2263MP replace CR6850T?
A: They serve similar functions but have different startup voltages and frequency settings. Verify application circuit before substituting.
