RS5RM SERIES

• Low Supply Current .......................................... Typ. 55µA (RS5RM3624A : V

• Standby Mode ..................................................... Istandby=Max. 1.0µA (RS5RMxxxxA)

• Low Voltage Operation Possible ....................... Operating Voltage V

• 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

• 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

• 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.

OUTLINE

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.

be monitored.

because internal circuits can be turned off by the chip enable function so that the standby current can be mini-

mized.

FEATURES

APPLICATIONS

(Ex. a fixed voltage of 3V can be output by a 3V battery).

The RS5RM Series are CMOS-based step-up DC/DC converter ICs equipped with a voltage regulator (VR) and

Since a voltage detector is built in these ICs, the potentials such as the output voltage of DC/DC converters can

In addition, these step-up DC/DC converter ICs are suitable for battery-powered and hand-held instruments
