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 (±10%) 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 converter 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.
