MIC2267YML-TR More Semiconductors - ICs by Microchip Technology
USB Power Maximizer
| Status: | Active |
|---|---|
| Series: | MIC2267 |
| RoHS: | Compliant |
The MIC2267 is a USB Power Maximizer which transfers the maximum power from the limited USB current source by shaping the input current limit profile. It incorporates a high efficiency, integrated synchronous step down regulator. Internal 150mΩ switches and adjustable operating frequency allows the MIC2267 to achieve greater than 90% efficiency across a broad load range. It replaces the USB current limit switch, 5V buck regulator and minimizes capacitance for many USB applications. The adjustable frequency control can be utilized to move harmonics away from sensitive frequency bands.
The MIC2267 allows the input current limit profile to be shaped for various applications. With a current mode control with external compensation, the MIC2267 transient response can be optimized over load and output capacitance making it highly flexible for many applications
Additional features include 1µA shutdown current, output current limit and thermal shutdown protection.
