The PMA series P2BU-xxxxELF is a family of cost effective 0.25 W single
output DC/DC converters. These converters are in an ultra miniature DIP8
case. Devices are encapsulated. High performance features: 1000VDC
input/output isolation, high efficiency operation, output voltage accuracy of
±3% maximum, input range of ±10% tolerance and low output ripple and
noise.
All specifications typical at Ta=25° nominal input voltage and full load unless otherwise specified
