The PSRW series is a family of cost effective 1.65~7.5W single output buck

DC-DC converters. These converters are encapsulated in a non conductive

black plastic 3-pin SIP case, continuous short circuit protection with

automatic restart, good line / load regulation and ultra low quiescence

current. Devices are filled up with flame retardant resin .Input voltages of

9~72, 14~72, 17~72, 20~72, and 36~72 with output voltage of 3.3, 5, 6.5,

7.2, 9 , 12 and 15Vdc. High performance features include high efficiency

operation up to 95%.
