High-efficiency switching regulator drop-in replacement has wide input range

Traco Power has released their new TSR 1.5E series of 1.5A step-down switching regulators, which are modern drop-in replacements for older, inefficient step-down regulators in the industry-standard SIP-3/TO-220 footprint. This new generation of non-isolated DC-DC converters is cost-optimised to help price-sensitive and high-volume requirements.

The series comprises three output models providing 7~36VDC Input range and 3.3, 5 or 12VDC outputs and up to 1500mA output currents. These drop-down regulators produce high-efficiency operation up to 97% and give full-load operation over an ambient temperature range of -40C to +85C without heat sinks, temperature derating, forced-air cooling or external capacitors. The switching regulators provide better output accuracy of 0.7% and a considerably lower standby current of only 15mA. Reliability is measured at a minimum of 6,800,000 hours per MIL-HDBK-217F ground benign and supported by a three-year warranty.

These products were created for a wide range of applications and are ideal for challenging thermal environments while lessening production costs with a more cost-efficient and reliable solution.
