TECHNICAL DATA
BIPOLAR LINEAR INTEGRATED CIRCUIT
52kHz 3A Step-Down DC/DC Converter.
The KIA2576 series are monolithic IC that design for a step-down
DC/DC converter,and own the ability of driving a 3A load without
additional transistor component. Due to reducing the number of
external component, the board space can be saved easily.

The internal compensation makes feedback control have good line
and load regulation without external design. Regarding protected
function,thermal shutdown is to prevent over temperature operating
from damage, and current limit is against over current operating of the
output switch. The KIA2576 series operates at a switching frequency
of 52kHz thus allowing smaller sized filter components than what
would be needed with lower frequency switching regulators.
