Efficiencies to 80%
The WF12S05/1000Z is an un-isolated 5 Watt DC/DC converter. An ultra wide
input voltage range facilitates operation from 12VDC and 24VDC battery
sources. Its relatively low cost makes the WF a particularly cost effective
solution for low power applications where I/O isolation is not required. The WF
features external output voltage trim of ±10%, regulation less than 1%, over
voltage protection and a fixed switching frequency of 100kHz. The result is a
75% efficient converter in a package measuring 2 x 2 x 0.38 inches.
The
LWM12S05/5000XC has an output power capability of 25 Watts and is supplied
in a package measuring just 2.56 x 3 x 0.83 inches. Key features include an
ultra wide 7 to 40VDC input voltage range, fixed 75kHz switching frequency,
remote on/off, output sense and output trim to ±10% of nominal value.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
