Test Procedure for the NCP3066 SEPIC DFN Evaluation Board

1. Connect the input DC voltage between DC input voltage node and DC ground nodes,

2. Place a jumper between DC ground and external enable.

3. Place a removable jumper as shown in Figure 2 as S1 to enable the part, S2 will disable

4. Shorting either S4 or S3 as shown in Figure 1 will place R7 and R6 current sense

5. Set the electronic load to 7.2 V in voltage mode or connect the appropriate LED string.

6. Monitor Iout and ensure the desired output current is 350 mA, 700 mA, or 1.05 A.

ensure the voltage is between 12V and 24V.

the part.

resistors in parallel with R8. The NCP3066 SEPIC demonstration PCB is configured to

output 350 mA when the LED load is set to 7.2 V. Placing one resistor in parallel with

R8 by connecting either S4 or S3 will increase the current to 700 mA. Once the

aforementioned steps are completed, both S4 and S3 will be shorted and the current limit

will increase to 1.05 A.
