DC/DC Converters
TSR-1SM Series, 1 A
Features
◆ 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
◆ Low standby current
◆ 3-year product warranty
The new TSR-1SM series models of step-down switching regulators have a high ef-
ficiency up to 96 % which allows full load operation up to +65°C ambient tempera-
ture without the need of any heat transmission layer.
Excellent output voltage accuracy (±2%) and low standby current (~1 µA) are fea-
tures that distinguish these switching regulators from linear regulators.
