DC/DC Converters Optimized To Drive LDO Regulators In Low Ripple Applications


5Vout models with +20% trim function enable optimal tuning

TRACO Power announces the expansion of their THN 15/20/30 WI series of 15, 20 and 30 Watt DC/DC converters in the standard 1.00 x 1.00 x 0.40 inch package with ultra-wide 4-1 Input ranges.

These new 15 / 20 / 30 watt 5Vout models with “-A1” suffix feature an extended trim range up to 6VDC.  The trim range enables trimming to the ideal voltage for LDO regulator applications, reducing power losses over the LDO while eliminating almost all ripple and noise.  This makes these converters ideal for providing isolation and regulation for circuits in low-noise applications.

Key Features

  • Ultra-wide 4:1 input range of 9-36 / 18-75 Vin.
  • Operating temperature range of -40°C to +70°C (up to 105°C with derating).
  • I/O isolation voltage 1600 VDC
  • 6-sided shielded metal case with isolated base plate

All models are safety approved to IEC/EN/UL 62368-1 and are qualified to meet EN 55032 Class A conducted emissions limits and will meet Class B limits with the addition of external components. Reliability is measured at >1.6 million hours per MIL-HDBK-2175 and backed by TRACO Power’s 3-year warranty.


Products are in stock and available through the TRACO Power’s global distribution network with manufacturing lead times of 12-14 weeks.
