TSR 1E Series POL Switching Regulators

TRACO Power's TSR 1E non-isolated POL DC/DC converters feature a wide 6 V_DC to 36 V_DC 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 V_DC and 3.3 V_DC 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.
