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 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.

Microsemi Corporation

DESCRIPTION
These high power 50 W Zener diodes represented by the JEDEC registered 1N2804 thru 1N2846B and 1N4557 thru 1N4564B series provide voltage regulation in a selection over a 3.9 V to 200 V broad range of voltages. They may be operated up to 50 W with adequate mounting and heat sinking with their low thermal resistance. These Zeners are also available in JAN, JANTX, JANTXV military qualifications. Microsemi also offers numerous other Zener products to meet higher and lower power applications.
