1.5 Amp high efficiency switching regulator

Traco Power has unveiled the TSR 1.5E series of 1.5 Amp 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 are cost optimized to support price sensitive and high-volume requirements.

The TSR 1.5E consists of 3 output models offering 7~36VDC Input range and 3.3, 5 or 12 VDC outputs and up to 1500mA output currents.

These drop-down regulators provide high efficiency operation up to 97% and provide full-load operation over an ambient temperature range of -40°C to +85°C without heat sinks, temperature derating, forced-air cooling or external capacitors.

The TSR 1.5E switching regulators offer better output accuracy of 0.7% and substantially 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 3 year warranty.

These products were designed for a broad range of applications and are well suited for challenging thermal environments while reducing production costs with a more cost-efficient and reliable solution.
