The Traco TSR 2N and TSR 3N are two step-down switching regulator series (2A and 3A) and a drop-in replacement for any TO-220 package linear regulators. These series come in a compact SIP-3 plastic package and complement our new generation of POL converters focusing strongly on a cost-efficient design while also improving on critical electrical specifications.
Output voltages are available between 1.2 and 15VDC. Depending on the model, the efficient design allows full load operation up to +95°C ambient temperature (at nominal Vin) without the need of any heat sink or forced cooling. The full operation temperature range is between –40°C to +95°C. The TSR 2N and TSR 3N switching regulators provide other significant features like short circuit protection, current limitation and under voltage lockout. Overall, they offer a broad application range in many environments and are especially suited for high volume projects where the series will help to reduce production cost by delivering not only a highly cost efficient but also reliable solution.
