MIC26601YJL-TR Description

The Micrel MIC26601YJL-TR is a constant-frequency, synchronous buck regulator featuring a unique adaptive on-time control architecture. The MIC26601YJL-TR operates over an input supply range of 4.5V to 28V and provides a regulated output of up to 6A of output current. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%, and the device operates at a switching frequency of 600kHz. The MIC26601YJL-TR offers a full suite of protection features to ensure the protection of the IC during fault conditions.
