MIC22205YML-TR More Semiconductors - ICs by Microchip Technology
4MHz 2A Synchronous Buck Regulator w/Programmable Frequency
| Status: | Active |
|---|---|
| Series: | MIC22205 |
| RoHS: | Compliant |
The Micrel MIC22205 is a high-efficiency, 2A, integrated switch, synchronous buck (step-down) regulator. The MIC22205 is optimized for highest efficiency, achieving more than 95% efficiency while still switching at 1MHz. The ultra-high speed control loop keeps the output voltage within regulation even under the extreme transient load swings commonly found in FPGAs and low-voltage ASICs. The output voltage is pre-bias safe and can be adjusted down to 0.7V to address all low-voltage power needs.
The MIC22205 offers a full range of sequencing and tracking options. The Enable/Delay (EN/DLY) pin, combined with the Power Good (PG) pin, allows multiple outputs to be sequenced in any way during turn-on and turn-off. The Ramp Control™ (RC) pin allows the device to be connected to another product in the MIC22xxx and/or MIC68xxx family, to keep the output voltages within a certain ∆V on start-up.
The MIC22205 is available in a 12-pin 3mm x 3mm MLF® with a junction operating range from -40°C to +125°C.
