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
Low standby current
3-year product warranty
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 ambi-
ent temperature without the need of any heat transmission layer. Excellent out-
put voltage accuracy (±2%) and low standby current (~1 µA) are features that
distinguish these switching regulators from linear regulators.
