TSR 1-0518SM

Non-Isolated DC/DC Converter (POL) • • • • • • • • • • TSR 1SM Series, 1 A SMD-package Up to 96% efficiency No thermal layer required Built in filter capacitors Operation temp. range –40°C to +85°C Short circuit protection Wide input operating range Excellent line / load regulation The new TSR-1SM series models of step-down switching regulators have a high efficiency up to 96% which allows full load operation up to +65°C ambient temperature without the need of any heat transmission layer. Excellent output voltage accuracy (±2%) and low standby current (~1 µA) are features that distinguish these switching regulators from linear regulators.
