Page 4: Quick Start Procedure
Voltage mode SEPIC evaluation kit TLD5099EP 2 Quick start procedure Quick start procedure The default configuration of the board has all additional features disabled. Jumper is placed in position 1-2. In this configuration, ENABLE signal must be applied on X18 (max. 45 V). If another output voltage is required, change the values of the voltage divider resistors R24, R25, and R26 according to the following equation: ... -
Page 5: Auto-Enable Configuration
Voltage mode SEPIC evaluation kit TLD5099EP 3 Auto-enable configuration Auto-enable configuration By placing the jumper X5 on position 2-3, the device starts without any external enable signal because pin EN (ENABLE) is connected directly to the positive rail (see Schematics for details). -
