General Description The AMS4155 is a 2A 420 kHz step-down converter in a thermally enhanced exposed paddle SO-8 package. External sync and compensation make the device very flexible for a wide range of applications and external components. Current mode control provides low ESR ceramic output capacitor stability with cycle by cycle current limit and fast transient response. Over-temperature shut down with hysteresis protects the device from excessive die temperatures. The converter has a 1.22V reference for low output voltage settings. Integrated fault protection protects the device in the case of an overload or over-temperature condition.
