1 / 6 page 2006. 7. 6 1/6 SEMICONDUCTOR 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.
