Voltage Regulators - DC DC Switching Regulators

synchronous buckCOT control4 A18 V inputSOT23-6600 kHz

TMI3254S is a compact synchronous buck regulator for converting 4.5 V to 18 V rails to adjustable lower voltages at loads up to 4 A.

Best for

  • Compact point-of-load buck supplies
  • 3.3 V and other adjustable low-voltage rails
  • Consumer and communications equipment

Avoid if

  • Input voltage can exceed 18 V during normal operation
  • A package larger than SOT23-6 is required for thermal margin
  • A formally qualified automotive-grade regulator is required

Check before use

  • Verify inductor peak current against the 8.5 A typical high-side current limit
  • Place ceramic input capacitors close to IN and GND
  • Keep FB routing away from LX and VOUT switching noise
