Why Choose OB2263MP?

  • Integrated Startup - Built-in high-voltage startup eliminates external startup resistors in many designs
  • Cycle-by-Cycle OCP - Protects power MOSFET from overcurrent on every switching cycle
  • SOT-23-6 Package - Ultra-compact for space-constrained charger and adapter PCBs
  • OB2263AMP Compatible - Direct replacement for OB2263AMP in existing designs
  • Multiple Protections - OVP, OCP, OTP, and UVLO for robust end-product reliability

Typical Applications

  • USB charger and wall adapter flyback SMPS
  • LED driver power supply controller
  • Offline flyback converter (85-265V AC input)
  • Set-top box and router auxiliary power supply
  • Industrial power supply repair and replacement

FAQ

Q: Is OB2263MP the same as OB2263AMP? Yes - OB2263AMP is an enhanced version with identical pinout and compatible electrical characteristics. OB2263MP is a direct drop-in replacement in most applications.

Q: What MOSFET is typically used with OB2263MP? Common choices include 2N60, 5N60, or 6N60 N-Channel MOSFETs rated for the application voltage (typically 600V for offline flyback).
