PWM STEP-UP DC/DC CONVERTER WITH
VOLTAGE REGULATOR AND DETECTOR
RS5RM SERIES
OUTLINE
NO. EA-018-0311
The RS5RM 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 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 the chip enable function so that the standby current can be mini-
mized.
FEATURES
• Low Supply Current ..........................................Typ. 55µA (RS5RM3624A : V
IN
=3.0V,at no load)
• Standby Mode.....................................................Istandby=Max. 1.0µA (RS5RMxxxxA)
Istandby=Max. 10.0µA (RS5RMxxxxB)
• Low Voltage Operation Possible .......................Operating Voltage V
IN
=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
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.

Why does the voltage of C46 become normal after replacing a larger capacitor?
After mounting the chips according to the circuit diagram, the voltage at VCC3V3 is not 3.3V, but 4.6V. After C46 is replaced from 22pF to 330pF, the voltage at VCC3V3 is 3.3V (the required voltage is...
