PWM STEP-UP DC/DC CONVERTER WITH VOLTAGE REGULATOR AND DETECTOR
RS5RM SERIES
OUTLINE
The RS5RM 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 PWM 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 t...
