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.
