National Semiconductor LM3590 Evaluation Board User Manual
The LM3590 Evaluation Board is designed to test and evaluate typical LM3590 application circuits. It features extra‑large pads for the input capacitor, current‑set resistor, and three white LEDs, as well as post holes for leaded pin‑sockets to simplify component changes and accommodate different package sizes.
The board is pre‑configured to deliver 20 mA to three series‑connected white LEDs with a minimum input voltage of 11.3 V. LED current is set by the external RSET resistor, and the EN pin provides an active‑high enable/shutdown function. The manual includes schematic details, component listings, and compliance information.
