BH□□PB1WHFV Series
The BH□□PB1WHFV regulator series can respond to changes in output current by switching to a state in which regulator
characteristics are ideal. The regulators cut power consumption by lowering their own current consumption to approximately
2 A when the application is operating in the standby state. During normal-current operation it will automatically switch to
high-speed operating mode. The IC's soft start function reduce the rush current that flows to the output capacitors during
startup. The HVSOF5 package, which features excellent heat dissipation, contributes to space-saving application designs.
