Non-Isolated DC/DC Converter (POL)

• Highly cost efficient design
• Pin compatible with TO-220 package 78xx linear regulators
• Operation temperature range –40°C to +85°C without derating
• Efficiency up to 97%

The TSR 1.5E is a 1.5 Ampere step-down switching regulator series and a

ent 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 ef- ficient but also reliable solution.
