TSR 2-0518

Non-Isolated DC/DC Converter (POL) • Ultra compact SIP package 0.55 x 0.30 x 0.40 inch • Up to 96% efficiency – No heat-sink required • Pin compatible with LMxx linear regulators • • Built in filter capacitors • • • Excellent line / load regulation Operating temperature range -40°C to +85°C Short circuit protection 3-year product warranty TSR 2 Series, 2 A The new TSR 2 series step-down switching regulators are drop-in replacement for inefficient LMxx linear regulators. A high efficiency up to 96% allows full load operation up to +67°C ambient temperature without the need of any heat-sink or forced cooling. The TSR 2 switching regulators provide other significant features over linear regulators, i.e. better output accuracy (±2%), lower standby current of 2 mA and no requirement of external capacitors. The high efficiency and low standby power consumption makes these regulators an ideal solution for many battery powered applications.
