DESCRIPTION
The PS2915-1 is an optically coupled isolator containing a
GaAs light emitting diode and an NPN silicon phototransistor
in one package for high density mounting applications. An ultra
small flat lead package has been provided which realizes a
reduction in mounting area of about 30% compared with the
PS28XX series.
APPLICATIONS
• DC/DC CONVERTER
• MODEM/PC CARD
