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.
