PWM STEP-UP DC/DC CONVERTER WITH
VOLTAGE REGULATOR AND DETECTOR
1
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 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.

=1.2V to 10V
High Output Voltage Accuracy.........................Fixed Output Voltage Accuracy±2.5%
High Voltage Detection Accuracy.....................±2.5%
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).
Soft Start Function, built-in Protection Circuits for Lx Driver
Phase Compensation Circuits built in
Pin for External Driver is equipped, and a large current output can be obtained.
Small Packages..................................................8pin SOP
FEATURES
APPLICATIONS
Power source for cameras, camcorders, and hand-held audio equipment.
Power source for small OA apparatus such as note book personal computers,and word processors.
Power source for hand-held communication appliances such as pagers,cordless telephones, and cellular phones.
