What is the function of LM2576?
The LM2576 is a voltage Regulator IC, it uses the Buck-converter topology to step-down and regulate higher level voltage values to lower level. It is of non-sync type and can take in an input voltage 40V maximum and source an output current of 3A maximum with a peak efficiency of 90%.
What is the difference between LM2576 and LM2596?
LM2596 Basics: The LM2596 series operates at a switching frequency of 150 kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators. This is as opposed to the 52-kHz Fixed-Frequency Internal Oscillator of the LM2576.
What is the output pin number of switching regulator IC LM2576 *?
Pin#02: Output.
Which IC is a low power variable voltage regulator?
Fortunately low dropout variable voltage regulators are available such as the National Semiconductor “LM2941T” Low Dropout variable voltage regulator which has a low dropout voltage of just 0.9 volts at maximum load.
What is XL6009?
XL6009 module is a non-isolated step-up boost voltage converter featuring adjustable output voltage, high efficiency. It converts input voltage of 5-32V DC to an output voltage of 4-38V DC.
What is ic7805?
IC 7805 is a 5V Voltage Regulator that restricts the output voltage to 5V output for various ranges of input voltage. It acts as an excellent component against input voltage fluctuations for circuits, and adds an additional safety to your circuitry. It is inexpensive, easily available and very much commonly used.
What is IC LM317?
The LM317 device is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%.
What is a dc/dc buck converter?
The buck converter is a very simple type of DC-DC converter that produces an output voltage that is less than its input. The buck converter is so named because the inductor always “bucks” or acts against the input voltage. When the switch is opened the supply current to the inductor is suddenly interrupted.
Why do I need a DC to DC converter?
DC-DC converters are widely used to efficiently produce a regulated voltage from a source that may or may not be well controlled to a load that may or may not be constant. Closed feedback loops maintain constant voltage output even when changing input voltages and output currents.
What does a boost converter do?
The boost converter is used to “step-up” an input voltage to some higher level, required by a load. This unique capability is achieved by storing energy in an inductor and releasing it to the load at a higher voltage.
What is the efficiency of the lm2576 buck converter?
The LM2576 is a voltage Regulator IC, it uses the Buck-converter topology to step-down and regulate higher level voltage values to lower level. It is of non-sync type and can take in an input voltage 40V maximum and source an output current of 3A maximum with a peak efficiency of 90%.
Is the lm2576 series a step down regulator?
The LM2576 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, 15 V, and an adjustable output version.
What is the value of the lm2576 inductor?
The value of the inductor can range from 47uH to 330uH based on the output required. A typical application circuit for LM2576 is show below. Since this is a switching circuit electrostatic interference should be kept in mind while designing the PCB of placing the components on a perf board.
