General Description The AMS4154 is a 2A, 330KHz, high voltage stepdown converter in a single thermally enhanced exposed paddle SO-8 package. Its wide 6V to 32V input voltage range is ideal for a wide range of applications. These applications include automotive battery requirements where the part achieves 2A of continuous output current for fast charge capability. 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.
