ACT8310 - Active-Semi

ACT8310 (ACT8309 - ACT8311) PWM Step-Down DC/DCs

The patent-pending ACT8309/ACT8310/ACT8311 are current-mode, fixed-frequency PWM, synchronous step-down DC/DC converters that are capable of delivering 1.5A with efficiency of up to 95%. These devices operate with a fixed frequency of 1.35MHz, minimizing noise in sensitive equipment as well as optimizing both efficiency and component size and cost. These dev.
