1 Description

1 Description

Evaluation board for high power LED application with TLD5099EP product in boost to battery topology.
Default configuration of the board is boost to battery topology without any additional features enabled. In this

configuration, it can deliver up to 21 W to the load with an eiciency above 84%. Auxiliary circuits, which protect
the DC-DC and the load during short to ground are present.

The board is also equipped with the following features that are enabled by jumpers:

• Output current adjustment trimmer

• Power derating circuitry

• Embedded PWM engine

• Cold crank survival circuit (CCSC)

2 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).

Jumpers are positioned as follows:

Table 2 Jumper position

X9 Close 2-3 Disable CCSC

X5 Close 2-1 External dimming enabled

X10 Close 2-1 Disable battery dependent current

3 Current adjustment

3 Current adjustment

The output current adjustment can be performed by changing the value of trimmer R15 with a screwdriver,
when X10 is closed in position 1-2 and X12 is closed. The output current can vary from 0 to 100% of the
maximum output current (in this evaluation board from 0 to 1 A). By removing jumper X12, the output current
will reach its maximum value. The PWM signal has to be applied as digital signal on connector X18 (max. 45 V).

Jumpers are positioned as follows:

4 Power derating (battery dependent current)

4 Power derating (battery dependent current)

The power derating acts by reducing V

(and thus the output current) when the battery voltage drops below

SET

8 V. It works better when R15 is trimmed to its maximum value. Otherwise a dierent derating profile is applied.
If a dierent derating profile is needed, R14 has to be changed. The aim is to have 1.6 V on pin SET when the
battery voltage reaches the desired threshold, below which the output current must decrease proportionally.

R14 can be calculated using:

R14 = R15 + R18 ⋅

BATT

1.6

− 1

(1)

V

where

• R15 = 10 kΩ

• R18 = 560 Ω
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).
Jumpers are positioned as follows:

5 Embedded PWM engine

5 Embedded PWM engine

The embedded PWM engine provides an internal PWM signal without any external dimming signal required. It
is enabled when jumper X5 is closed in position 2-3. If jumper X6 is open, the EN/PWMI pin is biased at 5 V and
then the duty cycle is 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:

X9 Close 2-3 Disable CCSC

X5 Close 2-3 Internal dimming enabled

X10 Close 2-1 Disable battery dependent current

X6 Closed Adjustable PWM dimming for position light

6 Cold crank survival circuit

6 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 le as preferred.

Note: The CCSC uses a Zener diode to adapt the output voltage to the required voltage for the TLD5099EP, so

that it can derate the eiciency performance.

11 Maximizing eiciency

11 Maximizing eiciency

This evaluation board has been designed to reach a fair compromise between eiciency performance and EM
emissions compliance.

Nevertheless, if the maximum eiciency is needed, the following actions should be considered:

1. Remove the snubber circuit R5, C25 or choose a lower value for the capacitor C25 (for example, 470 pF)

2. Bypass the whole EMI filter by bridging the jumpers X1, X14 and X16

3. Bypass the output ferrite beads L3 and L5

4. Replace the main inductor L6 with one that boasts a lower parasitic DC resistance, for example,

• Vishay IHLP6767GZER470M8A

• Bourns SRP1770TA-470M

5. Turn o the CCSC by placing jumper X9 on position 2-3

6. Bypass gate resistor R8

12 Minimizing EM emissions

12 Minimizing EM emissions

This evaluation board has been designed to reach a fair compromise between eiciency performance and EM
conducted emissions compliance. Furthermore, this evaluation board can fulfill the class V of the CISPR25 in
conducted emissions from 150 kHz to 108 MHz.

Nevertheless, if the minimum EM emission is required, the following actions should be considered:

1. Choose a higher value for the capacitor C25 (for example, 2.2 nF)

2. Include the whole EMI filter by removing bridges from the jumpers X1, X14 and X16

3. Replace the 0 Ω resistor R8 with a higher value such as 10 Ω or 22 Ω

4. Replace the main inductor L6 with a shielded one (for example, Cyntec VCHE106G-470MS6) and connect

the shield to ground

5. Connect the CHASSIS TERMINAL with a short piece of wire as close as possible to the test ground plane

where the board is placed
