The GS-R400 series is a versatile family of high current, high voltage step-down switching voltage regulators from Panasonic. This series features 4A of maximum output current, 46V of maximum input voltage and 4V of maximum drop-out voltage. In addition, this series also provides soft start, remote logic inhibit/enable, remote output voltage sense, non-latching overload and short circuit protection as well as crow-bar output overvoltage protection.
The GS-R400 series is a versatile family of high current, high voltage step-down switching voltage regulators. The integral heatsink allows for large power handling capability and provides effective shielding to minimize EMI. The family includes fixed output voltage types and programmable versions with features such as remote logic inhibit/enable and remote output voltage sense.
