In the Adjustable version of the LM switching regulator this pin is the direct input of the error amplifier and the datadheet network R2 connected externally to allow programming of the output voltage.
Functional operation above the Recommended Operating Conditions is not implied. Inductor The magnetic components are the cornerstone of all switching power supply designs In many cases, the power dissipated by the LM regulator is so. The output ripple voltage value ranges from 0. satasheet
LM2575-5.0 Buck Converter overview
The reverse voltage rating of the diode should be at least 1. Stresses exceeding Maximum Ratings may damage the device.
Feedback LM mH Output External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. Maximum Ratings are stress ratings only.
These devices are available in fixed output voltages of 3. Undervoltage Lockout Circuit for http: Output Voltage Ripple and Transients Source of the Output Ripple Since the LM is a switch mode power supply regulator, its output voltage, if left unfiltered, will contain a sawtooth ripple voltage at the switching frequency. These regulators were designed to minimize the number datssheet external.
For a robust design, the diode should have a current rating equal to the maximum current limit of the LM to be able to withstand a continuous output short.
Copy your embed code and put on your site: The LM series of regulators are monolithic integrated circuits. See general marking information in the device marking.
When the LM is used as shown in the Figure 14 test circuit, system performance will be as shown in system parameters section. Download datasheet Kb Share this page. Elcodis is a trademark of Elcodis Company Ltd.
LM Buck Converter equivalents, price and datasheet
See detailed ordering and shipping information in the package. By grounding the feedback pin, the regulator senses the inverted output voltage and regulates it. All other trademarks are the property of their respective owners. Table 1 and Table 2 of this Indicator Selection Guide shows some examples of different manufacturer products suitable for design with the LM All circuits of this series are.
To simplify the inductor selection process, an inductor selection guide for the LM regulator was added to this data sheet Figures 17 through For stable operation, the capacitor must satisfy the For a robust design the diode should have a current rating equal to the maximum current limit of the LM to be able to withstand a continuous output short B.
Output Capacitor Selection C out A. Unless otherwise specified for the Device listed in bold are available from ON Semiconductor.
Adjustable Version Output Voltage Range dwtasheet 1. This picture does not show the complete circuit. In many cases, the power dissipated by the LM regulator is so low, that no heatsink is required or its size could be reduced dramatically.
