The A1505S-1WR3 from MORNSUN is an Isolated Buck DC-DC Converter that converts a DC input voltage of 13.5 - 16.5 V to a DC output voltage of ±5 V. It delivers an output power of up to 1 W and has an efficiency of over 76% under full load drive conditions. This DC-DC converter offers an unregulated output with input-to-output isolation of 1.5 kV. It integrates a continuous short-circuit protection function to prevent over-current-related damages, a built-in EMC (Class B) filter that guarantees the excellent rejection of electromagnetic interference (EMI) and has undergone UL flame-retardant tests for the safety of operation. This RoHS-compliant DC-DC converter is available in a through-hole package that measures 19.65 x 6.00 x 10.16 mm.
