TSR 1.5-2450E

Non-Isolated DC/DC Converter (POL) • • Highly cost efficient design • Operation temperature range –40°C to +85°C without derating • • • • • Efficiency up to 97% TSR 1.5E Series, 1.5 A Pin compatible with TO-220 package 78xx linear regulators Wide input operating range 7-36 VDC Short circuit protection Excellent line / load regulation 3-year product warranty The TSR 1.5E is a 1.5 Ampere step-down switching regulator series and a drop-in replacement for inefficient LM78xx linear regulators. This series comes in a compact SIP-3 open frame package and complements our existing POL portfolio with a series focusing strongly on a cost efficient design while maintaining our quality standards. There are 3 output voltages available: 3.3, 5.0 and 12VDC. The effective design allows full load operation up to +85°C ambient temperature without the need of any heat sink or forced cooling. The TSR 1.5E switching regulators provide other significant features over linear regulators, i.e. better output accuracy, lower standby current and no requirement of external capacitors. The TSR 1.5E series offers a broad application range in many environments and is 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.
