... The fast transient response of the DeCAPitator can make up for the slow response time of many switching DC-DC converters. Although the HIP6200 serves as a simple replacement for large output capacitors for any dynamic load especially useful in stabilizing the CPU core voltage in portable computer applications, where size and effi ...

... The response time of the HIP6200’s linear regulators (100ns typical) are fast enough to help with the leading edge spike. Output voltage deviations during the converter response time are reduced with the HIP6200 since it helps supply the load while the inductor current slews. BATTERY POWER ...
