GENERAL DESCRIPTION
The AMS4154 is a current mode control part which provides low ESR ceramic output capacitor stability and fast transient response. Fault protection includes a “hiccup” current limit and thermal protection with hysteresis to protect the device from excessive die temperatures. With an external VREF and using only minimum number of readily available external components to compensate, AMS4154 is very flexible for a wide range of applications that requires a 2A step-down DC/DC solution.
