DC/DC converters optimised to drive LDO regulators

TRACO Power has expanded its THN 15/20/30 WI series of 15, 20 and 30W DC/DC converters in the standard 1.00 x 1.00 x 0.40” inch package with ultra-wide 4-1 Input ranges.

These 15 / 20 / 30W 5Vout models with “-A1” suffix feature an extended trim range up to 6VDC. The extended trim function up to 6 VDC make these DC/DC converters suitable for LDO regulator applications, reducing power losses over the LDO while eliminating almost all ripple and noise components and provide a clean 5 VDC output voltage - providing isolation and regulation for circuits in low-noise applications

These compact, high-performance 15, 20 and 30W converters are the latest generation of DC/DC converters and feature: an ultra-wide 4:1 input range of 9-36 / 18-75 Vin.; full-load operating temperature range of -40°C to +70°C (up to 105°C with derating); input to output isolation of 1,600 VDC and a 6-sided shielded metal case with an insulated 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.
