RS5RM4943A-T1 PWM STEP-UP DC/DC CONVERTER WITH VOLTAGE REGULATOR AND DETECTOR

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.

NTE4943 Surge Clamping, Transient Overvoltage Suppressor Bidirectional

Description:
The NTE4900 series of silicon Transient Suppressors designed to protect voltage sensitive components from high energy voltage transients. Transient over voltage suppressor devices have become very important as a consequence of their high surge capability, extremely fast response time, and low incremental surge resistance (Rs).

Application:
The NTE4900 series has a peak pulse power rating of 1500 watts for one millisecond. Can protect integrated circuits, hybrids, CMOS, MOS, and other voltage sensitive components in a broad range of applications such as telecommunications, power supplies, computers, automotive, industrial and medical equipment.
