The DeCAPitator is designed to reduce the number of bulkcapacitors required at the output of a switching DC-DCconverter powering a microprocessor in a portablecomputer. It contains two high-speed linear regulators whichare only active if the processor core voltage is disturbed by afast moving load transient. Figure 1 shows the HIP6200 in itstypical application. Refer to the HIP6200 data sheet [1] fordetailed specifications.
