The PSR1-S series is a family of cost effective 1.5~5W single output buck
DC-DC converters. These converters are encapsulated in a non-conductive
black plastic package 3-pin SIP case, continuous short circuit protection
with automatic restart and good line / load regulation. Devices are filled up
with flame retardant resin .Input voltages of 4.75~18,and 6.5~18 with output
voltage of 1.5, 1.8, 2.5, 3.3, 5, Vdc. High performance features include high
efficiency operation up to 94%. Standard features include an input range of
4.75~18Vdc tolerance and low output ripple and noise.
All specifications typical at Ta=25°C, nominal input voltage and full load unless otherwise specified
