TSR 1E, TSR 2N, and TSR 3N Series Switching Regulators

TRACO Power TSR 1E, TSR 2N, and TSR 3N are step-down switching regulator series designed as efficient, drop-in replacements for traditional linear regulators, such as 78xx and TO-220 package types. All models are housed in a compact SIP-3 plastic package and complement the portfolio of point-of-load (POL) converters from TRACO Power, with a strong focus on cost-efficient design without compromising quality standards. The TSR 1E delivers up to 1 A and supports full load operation up to +60°C without requiring heat sinks or forced cooling. The TSR 2N and TSR 3N offer higher output currents of 2 A and 3 A, respectively, with input voltage ranges from 4.6 V_DC to 36 V_DC and output voltages between 1.2 V_DC and 15 V_DC, while also enhancing critical electrical performance parameters.
