• Manufacturer Part Number: SPI-8001TW_11
• Description: 2-Output, Step-down Switching Mode
• Manufacturer: SANKEN [Sanken electric]

■Electrical Characteristics
*1: Electrical characteristics show the characteristic ratings guaranteed when operating the ICs under the measurement conditions described in the above table.
*2: Efficiency is calculated from the following formula.
*3: Pin 6 and pin 11 are the SS pins. Soft start at power on can be performed with capacitors connected to these pins. The outputs can also be turned ON/OFF with these pins. The
