YB1696

The YB1696 series are monolithic integrated circuits that provide all the active functions for a step-down DC/DC converter, capable of driving a 3A load without additional transistor component. Requiring a minimum number of external component, the board space can be saved easily. The external shutdown function of YB1696 can be controlled by TTL 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 YB1696 series operates at a switching frequency of 150KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed +4% tolerance on output voltage under specified input voltage and output load conditions, and +15% on the oscillator frequency. The output version included fixed 5V and an adjustable type. The package is available in a standard 5-lead TO-263(S).
