DC/DC Converters Optimized to Drive LDO Regulators


5Vout models with +20% trim function enables optimal tuning of 5V Low Drop-Out Linear Regulators for Extremely Low Ripple & Noise

San Jose, Calif. – 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 extended trim function up to 6 VDC make these DC/DC converters perfect 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. This makes these converters ideal for providing isolation and regulation for circuits in low-noise applications

These compact, high-performance 15, 20 and 30 Watt DC/DC 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.

Products are in stock and available through the TRACO Power’s global distribution network with manufacturing lead times of 12-14 weeks. Please see www.tracopower.us/thn-a1 for specifications, drawings and safety documentation.
