5A, PWM Step-Down DC/DCs in TDFN GENERAL DESCRIPTION
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 devices feature very low-resistance power
MOSFET and 100% duty cycle operation, making them ideal choices for portable applications requiring...
