AN30181A
AN30181A
General-purpose power management LSI
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 of external parts.
Output voltages are 1.2 V and 1.8 V. Each maximum current is 0.8 A.
This LSI has a LDO circuit, external Pch-MOSFET gate drive circuits and a reset circuit of input power supply voltage.
AN30181A is a power management LSI which has step-down DC-DC converters (2-ch) that employs hysteretic control system.
