Driving Dual LP5024 Application Example 8.2.1 Design Requirements Set the LED current to 15mA using the RIREF resistor. 8.2.2 Detailed Design Procedure LP50xx 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 external resistor (RIREF): R IREF =KIREF × V IREF I SET (2) LP5018, LP5024 SLVSEB8C – OCTOBER 2018 – REVISED JULY 2024 www.ti.com 40 Submit Document Feedback Copyright © 2024 Texas Instruments Incorporated Product Folder Links: LP5018 LP5024 |
