VOUT Voltage Setting in Constant Voltage Mode:

For a voltage regulator, the output voltage can be set by selecting the values RFB1, RFB2

according to the following equation. IFBL value is about 30uA .

VOUT =

VFBH-FBL

Input Voltage UVLO and Current Limitation:

Input under voltage shutdown levels EN/INUVLO can both be defined through an external

resistor divider. The two inputs (IIN1, IIN2) can be used to limit the Input current. IINmax. If the

input current limitation is not used, it needs to short IIN1 and IIN2 to VIN and short RIN.

Following are the equations and figure for these protections. 10kΩ is suggested for R2.
