 SOP-8/EP (Exposed Pad) Package

The ACT4070 is a current-mode step-down

DC/DC converter that generates up to 3A output

current at 400kHz switching frequency. The

device

utilizes

Active-Semi’s

proprietary

ISOBCD30 process for operation with input

voltage up to 30V.

Consuming only 6

μA in shutdown mode, the

ACT4070 is highly efficient with peak efficiency at

95% when in operation. Protection features

include

cycle-by-cycle

current

limit,

thermal

shutdown, and frequency fold back at short circuit.

The device also includes an internal soft start

function to prevent overshoot.

The ACT4070 is available in SOP-8/EP exposed

pad package and requires very few external

devices for operation.
