DESCRIPTION
An adjustable Soft-Start by an external capacitor prevents the excessive inrush current in startup. The feature increasing efficiency at light loads allows the device to be used in the energy-saving applications. The ICs integrate phase compensation circuit which reduces the number of external components and simplifies the design of customer application. The IC has the EN pin that turns the regulator on or off, and achieves low power consumption requirements. The package of NR117K is the HSOP8 with an exposed thermal pad on the back side.FEATURES
