VFM STEP-UP DC/DC CONVERTER WITH  
VOLTAGE REGULATOR AND DETECTOR  
NO. EA-024-0204  
RS5RJ SERIES  
OUTLINE  
The RS5RJ series are CMOS-based step-up DC/DC converter ICs equipped with a voltage regulator (VR) and  
a voltage detector (VD). 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 the chip enable function so that the standby current can be mini-  
mized.  
FEATURES  
...........................................  
•
Low Supply Current  
Typ. 15µA (RS5RJ3624A : VIN=3.0V,at no load)  
Istandby=Max. 1.0µA (RS5RJxxxxA)  
.....................................................  
•
Standby Mode  
Istandby=Max. 10.0µA (RS5RJxxxxB)  
Operating Voltage VIN=1.2V to 10V

Low Voltage Operation Possible  
High Output Voltage Accuracy  
.........................  
Fixed Output Voltage Accuracy 2.5ꢀ  
2.5ꢀ  
...................  
High Detector Threshold Accuracy  
Output Voltage can be set at User's request (refer to Selection Guide).  
Voltage close to battery's voltage can be output because these ICs are of a step-up / step-down type  
(Ex. a fixed voltage of 3V can be output by a 3V battery).

•
Built-in Protection Circuits for Lx Driver  
Pin for External Driver is equipped, and a large current output can be obtained.

Small Package  
8pin SOP  
APPLICATIONS  
•
•
•
Power source for cameras, camcorders, and hand-held audio equipment.  
Power source for small OA apparatus such as note type personal computers,and word processors.  
Power source for hand-held communication appliances such as pagers,cordless telephones, and cellular phones.
