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.

FEATURES

? Low Supply Current ..........................................TYP. 55μA (RS5RM3624A : VIN=3.0V,at no load)

? Standby Mode.....................................................Istandby=MAX. 1.0μA (RS5RM××××A)

Istandby=MAX. 10.0μA (RS5RM××××B)

? Low Voltage Operation Possible.......................Operating Voltage VIN=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 Users request (refer to Selection Guide).

? Voltage close to batterys 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.
