ESCRIPTIONS
The 1500LN, single output power modules are 8 to 15 watt
DC/DC converters available in a single output configuration
providing 2.0 VDC to 15 VDC outputs and are fully compatible to
Tyco series LW010 and LW015 providing both positive and
negative on/off logic. These 400kHz, switching converters are
available 48 VDC inputs with efficiencies up to 88%. Offering
pin for pin and full functionality to the Tyco LW series these
converters are the only true second source available in the
market.
