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 convert-

er, 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.

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.
