GENERAL DESCRIPTION

The patent-pending ACT8309/ACT8310/ACT8311

are current-mode, fixed-frequency PWM, synchro-

nous 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 requir-

ing a 3.0V or 3.3V rail to be generated from a Li+

battery.

The ACT8311 is capable of supplying up to 1.5A of

output current, while the ACT8309 and ACT8310

are capable of supplying up to 900mA and 1.2A,

respectively. All three devices have adjustable out-

put voltages that are programmable down to 1.2V.
