Typical Application (continued)
Figure 73. Driving Dual LP5036 Application Example
9.2.1 Design Requirements
Set the LED current to 15 mA using the RIREF resistor.
9.2.2 Detailed Design Procedure
The LP503x device scales up the reference current (IREF) set by the external resistor (RIREF) to sink the output
current (IOUT) at each output port. The following formula can be used to calculate the target output current
