EA4524YH Datasheet, PDF (6/16 Pages) Active-Semi, Inc – 40V/3.5A Buck Converter with Dual Output and Separated Over Current Protection

FUNCTIONAL DESCRIPTION
CLK Mode
There are three clock modes that depend on the
mode pin configuration. During power up, device
checks MODE pin condition (floating, 82k resistor to
ground or grounded) to decide which mode (native,
master or slave) device should operate in.
If only single ACT4524 is required, mode pin can be
left float, and ACT4524 runs at native mode using
internal oscillator clock.
For high load current application (>3.5A), it's
possible to use two ACT4524 to operate in parallel
with one device as master to provide clock for the
other (slave). Two devices operate on the same
frequency, but in opposite phase to optimize supply
loading and EMI performance.
