VFM STEP-UP DC/DC CONVERTER WITH VOLTAGE REGULATOR AND DETECTOR RS5RJ SERIES APPLICATION MANUAL NO.EA-024-0006 VFM STEP-UP DC/DC CONVERTER WITH VOLTAGE REGULATOR AND DETECTOR RS5RJ SERIES OUTLINE The RS5RJ series are step-up DC/DC converter ICs equipped with a voltage regulator (VR) and a voltage detector (VD) by CMOS process. Each of these step-up DC/DC converter ICs consists of a VFM DC/DC converter, a linear regulator and a voltage detector. These ICs are output-voltage-fixed type regulators which function as a linear regulator when input voltage is high, and as step-up DC/DC converter + linear regulator when input voltage is low, by using an inductor, a diode and a capacitor as external parts for the ICs. Since a voltage detector is built in these ICs, the potentials such as the output voltage of DC/DC converters can be monitored. In addition, these step-up DC/DC converter ICs are suitable for battery-powered and hand-held instruments because internal circuits can be turned off by...
