Page 4: Quick Start Procedure
Voltage-mode boost to ground evaluation kit TLD5099EP 2 Quick start procedure Quick start procedure The default configuration of the board has all additional features disabled. Jumper is positioned in 1-2 position. In this configuration ENABLE signal has to be applied on X18 (max 45 V). If another output voltage is required, the voltage divider composed of R24, R25, R26 must be changed according to the rule that a 300 mV dropout should be present across R25 when the desired voltage is present in the output. -
