TECHNICAL DATA

Revision No : 1

150kHz 1A Step-Down DC/DC Converter.

The KIA2575 series are monolithic IC that design for a step-down

DC/DC converter,and own the ability of driving a 1A load without

additional transistor component.

Due to reducing the number of

external component, the board space can be saved easily.

The external shutdown function can be controlled by logic level and

then come into standby mode.

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 KIA2575 series operates at a switching frequency

of 150kHz thus allowing smaller sized filter components than what

would be needed with lower frequency switching regulators.
