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

=3.0V,at no load)

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

Istandby=Max. 10.0µA (RS5RMxxxxB)

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

=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.
