Technical content
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.
