Page 2: Description
1 Description Description Evaluation board for high power LED application with TLD5099EP product in boost to ground topology. Default configuration of the board is boost to ground topology without any additional features enabled. In this configuration, it can deliver up to 13 W to the load with an efficiency above 90%. Auxiliary circuits, which protect the DC-DC and the load during short to ground, are present. - Page 3 Boost to ground evaluation kit TLD5099EP 1 Description Figure 2 Simplified schematic Table 1 Performance summary Parameter Conditions Value Input supply voltage Jumper X9 in position 2-3 (CCSC deactivated) 8 V to 27 V Parameter degradation below 6.5 V Down to 6.5 V for less than 2 s...

Page 4: Quick Start Procedure
Boost to ground evaluation kit TLD5099EP 2 Quick start procedure Quick start procedure The default configuration of the board has all additional features disabled. In this configuration the output current cannot be adjusted. The PWM signal has to be applied as digital signal on connector X18 (max. 45 V). -
Page 5: Current Adjustment
Boost to ground evaluation kit TLD5099EP 3 Current adjustment Current adjustment The output current adjustment can be performed by changing the value of trimmer R15 with a screwdriver, when jumper X10 is closed in position 1-2 and jumper X12 is closed. The output current can vary from 0 to 100% of the maximum output current (in this evaluation board from 0 to 350 mA). -
Page 6: Power Derating (Battery Dependent Current)
For example, if the power derating should start when the battery voltage drops under 12 V, R14 must be replaced with a 68 kΩ 0603 resistor (please refer to the TLD5099EP datasheets for more information). The PWM signal has to be applied as digital signal on connector X18 (max. 45 V). -

100%. Closing jumper X6, the duty cycle is adjustable by means of trimmer R4. The PWM frequency is set to 350 Hz. If another PWM frequency is needed, C28 must be changed to a proper value (please refer to the TLD5099EP datasheets for more information). Jumpers are positioned as follows:... -
Page 8: Cold Crank Survival Circuit
This feature helps the system to survive LV124 test E11 “severe test pulse”, when the input voltage drops below 4.5 V, which is the minimum input voltage for the TLD5099EP. This circuit feeds back the device with the output voltage when the input voltage drops. To activate this feature, close jumper X9 in position 1-2. Other settings can be left as preferred. -
