TRACOPOWER Switching Regulator Through Hole SIP Package 9V dc -9 V dc Output Voltage 1 A Output Current TSRN 1-2490

TRACOPOWER TSRN 1-2490 is a Switching Regulator designed as a 1A step-down converter with a through-hole mount in a SIP package. It supports output voltages of 9V dc and -9V dc with high efficiency of up to 88%, enabling full load operation without requiring heatsinks or forced air cooling. This makes it highly suitable for industrial, electronic, and energy-sensitive applications.

The regulator features a broad input voltage range up to 42V dc, with a minimum input voltage of 10.5V, thus allowing flexible integration in various power systems. It offers excellent line regulation (±0.2 %) and load regulation (±0.4 %) for stable and precise output voltage delivery.

Robust built-in protections include over-temperature and short circuit safeguards to enhance device reliability. The low standby current of about 1 mA for 5.0 V output models contributes to energy efficiency. The unit operates within a temperature range from -40°C to 85°C, ensuring suitability for challenging environmental conditions.

The SIP package fits the TO-220 footprint, facilitating ease of replacement or upgrade in existing designs. The device complies with RoHS standards, and ensures long-term reliability with a Mean Time Before Failure (MTBF) of 6 million hours measured according to MIL-HDBK-217 at 25°C. Note that for input voltages higher than 36 V dc, an input capacitor of 22 μF/50 V is recommended.

Designed with a wide input voltage range up to 42 VDC to support flexible power sources. Achieves 88% efficiency, allowing operation without a heatsink or forced air cooling. Includes over-temperature and short-circuit protection for enhanced reliability.

Features excellent line regulation of ±0.2 % and load regulation of ±0.4 % ensuring stable output. Operates safely within a temperature range of -40°C to 85°C, suitable for diverse environments. Incorporates built-in filter capacitors and low standby current making it ideal for energy-sensitive circuits.

Complies with RoHS standards and comes in a SIP package compatible with TO-220 footprints. Mean time before failure (MTBF) is rated at 6,000,000 hours, ensuring long-term durability.

This switching regulator is commonly used in industrial electronics, power management circuits, laboratory equipment, and consumer electronic devices requiring reliable DC voltage conversion.
