MITSUBISHI SEMICONDUCTOR
M57184N-715
UN-INSULATING TYPE DC-DC CONVERTER
DESCRIPTION M57184N-715 is the un-insulating type DC-DC converter which the rectification voltage of AC200V system can direct input. A power supply (15V, 350mA, and 5V and 200mA) can be obtained only by attaching a small number of external parts, such as an electrolysis capacitor and a chalk coil.
