LM2567
LAN DC DC Converter
General Description
The LM2567 DC DC converter is intended for use in LAN
applications as a power supply for the DP8392 Coaxial
Transceiver The converter may be operated from an input
voltage of 5V (g10%) to 15V It provides an isolated output
of b9V for loads of up to 180 mA with an efficiency of 78%
(typical) The few external components required for the con-
verter are completely specified within this datasheet
Protection features for the LM2567-based DC DC converter
include thermal and current limit Undervoltage lockout and
soft-start are incorporated to minimize the inrush current
during start-up
Features
Y Wide input voltage range 5V to 15V
Y Tight line regulation 0 5% (typ)
Y Output voltage tolerance g5%
Y Few external components required
Y Surface-mount packaging
Y Fixed switching frequency of 52 kHz
Y Current-mode operation for improved
sponse
