Common device features
| Title | Description |
|---|---|
| PMBus | Learn how a buck converter with PMBus can enhance performance in your design. |
| BOOT capacitor | Certain applications require that output voltage regulation be maintained shen the input voltage is only slightly higher than the output voltage. For a buck converter, these low headroom operating conditions require high duty cycle operation that may approach 100%. |
| How to control turn on/off thresholds in voltage regulators | When using a voltage regulator, it often happens that the converter will attempt to regulate the output even before the voltage on its input has reached the acceptable design level. As a result, in this condition, the converter will demand more current from the power supply, potentially current-limiting the power source. |
| Understanding ECO-MODE™ operation | Learn how to reduce switching losses and increase efficiency at low output current with Eco-Mode operation. |
Applications
| Title | |
|---|---|
| Generate a negative output voltage | Watch as Anston discusses how to transform the LM4360x and LM4600x synchronous buck converters into inverters for applications that require a negative input voltage.. |
| Adding hysteresis to a buck converter | Use the calculator to add Enable hystersis to your buck converter design |
Maximizing performance
