Description:
M57120L is a non-isolated
DC-to-DC converter with a built-in
transformer. Wide range of input
voltage (DC 113V-400V) enables
direct connection to rectified 120V
and 240V AC. This device is best
suited for use as a pre-regulator
for standard DC-to-DC converters.
Features:
u Wide Range of Input Source
Voltage (113V-400V DC)
u Built-in Surface-mount
Transformer
u SIP Structure Enables Efficient
use of PCB Area
Applications:
u Power Source for Standard
DC-to-DC Converters
u Pre-regulator
