TSR 1E Series POL Switching Regulators

TRACO Power’s 1 A POL switching regulator is available in a cost-effective design

Image of TRACO Power TSR 1E Series POL Switching RegulatorsTRACO Power's TSR 1E non-isolated POL DC/DC converters feature a wide 6 VDC to 36 VDC input voltage range in the standard SIP-3 package (LMxx compatible). The cost-optimized design maintains high-quality standards with full load operation up to +60°C with an MTBF of one million hours and backed by a three-year warranty. The wide input range makes these POL converters versatile solutions for many applications in battery-powered and distributed power applications where different input voltages are required. The TSR 1E series was specifically designed for higher volume, price-sensitive 5 VDC and 3.3 VDC applications where cost reduction is a critical concern with no sacrifice in performance.

High efficiency up to 92% enables full-load, convection-cooled operation up to +60°C ambient operating temperatures with no heat sink required and makes them ideal drop-in replacements for less efficient LMxx linear regulators. With a 1 A output current and standard features such as low standby current, precise regulation and protection against short circuit, overvoltage, and overload make the TSR family a great option for many applications.

Features
  • Wide 6:1 input voltage range: 6 VDC to 36 VDC
  • Operates over a wide range of bus and battery voltages
  • Very high efficiency up to 92%
  • Excellent line/load regulation
  • Low standby current
  • Protection against short circuit, overvoltage, and overtemperature
  • Pin compatible with LMxx linear regulators (SIP-3)
  • 3-year warranty
