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
