Traco Power has launched 1.5A open frame point of load (POL) switching regulator to take on a part from Analog Devices

The TSR 1.5E is a 1.5A step-down switching regulator series with an efficiency of 97 percent that is  drop-in replacement for the LM78xx linear regulators from ADI in a TO-220 package.

The series comes in a compact SIP-3 open frame package with a focus on cost efficient design. There are 3 output voltages available at 3.3, 5.0 and 12VDC and an output from 7 to 36V. The  design allows full load operation from –40°C up to +85°C ambient temperature without the need of any heat sink or forced cooling.

The TSR 1.5E switching regulator series provides better output accuracy, lower standby current and no requirement of external capacitors compared to a linear regulator. The TSR 1.5E is aimed at a wide range of applications, especially high volume projects where the series will help to reduce production cost by delivering not only a highly cost efficient but also reliable solution.
