CM2593 Datasheet | Champion

DESCRIPTION The CM2593/P is a monolithic integrated circuit that provide all the active functions for a step-down switching regulator, capable of driving a 2A load without additional transistor ponent. Requiring a minimum number of external ponent, the board space can be saved easily. The external shutdown function can be controlled by TTL logic level and then e into standby mode. The internal pensation 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 CM2593/P operates at a switching frequency of 150Khz thus allowing smaller sized filter ponents than what would be needed with lower frequency switching regulators. Other features include a guaranteed +4% tolerance on output voltage under specified input voltage...
