说明
-
MIC22205YML EV, Evaluation Board for the MIC22205 is a high-efficiency, 2A, integrated switch, synchronous buck (step-down) regulator. It is frequency programmable up to 4MHz. The MIC22205 achieves more than 95% efficiency and switches 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 is adjustable down to 0.7V. The MIC22205 offers a full range of sequencing and tracking options. The Enable/Delay (EN/DLY) and Power Good (PG) inputs allow versatile turn-on and turn-off sequencing across multiple devices. The Ramp Control (RC) input allows start-up voltage tracking, either directly or ratio-metrically
