Non-isolated step-down DC-DC converters can linear types

Traco Power's TSR Series non-isolated step-down DC-DC converters are now stocked by Mouser. The high-efficiency point of load (PoL) switching regulators are suitable for replacing linear converters. The TSR-1 series has a high efficiency of up to 96% which allows full load operation up to +60C without the need for heat sink or forced cooling. Other features which distinguish TSR-1 over linear regulators include superior output accuracy (±2%) and lower standby current of 2mA. Additionally, TSR-1 requires no external capacitors. The series is ideal for battery-powered applications, says the company.
