AN30185A is a power management LSI which has DC-DC step down
regulators (2-ch) that employs hysteretic control system. By this system, when load current changes suddenly, it responds at high speed and minimizes the changes of output voltage. Since it is possible to use capacitors with small capacitance and it is unnecessary to use parts for phase compensation, this IC realizes downsizing of set and reducing in the number o...
