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%.
All specifications typical at Ta=25°C, nominal input voltage and full load unless otherwise specified
