GENERAL DESCRIPTION
The patent-pending ACT8310/ACT8311 are currentmode, 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 devices feature very low-resistance power MOSFET and 100% duty cycle operation, making them ideal choices for portable applications requiring a 3.0V or 3.3V rail to be generated from a Li+ battery.
