TMI3255T is an adjustable 5 A synchronous buck converter for 4.5 V to 18 V input rails, using 600 kHz constant-on-time control in an SOT23-6 package.

Best for

  • Compact 5 A buck power rails
  • 3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V, or 1.0 V rails
  • Consumer and communications equipment

Avoid if

  • Input voltage can exceed 18 V during normal operation
  • A documented lifecycle status or automotive qualification is required
  • The application requires a package with substantial thermal dissipation capability

Check before use

  • Input overvoltage and surge conditions
  • Inductor saturation and RMS-current ratings
  • Output capacitor effective capacitance and ripple current
  • SOT23-6 thermal performance on the target PCB
