Table 4. Jumper Description
Jumper Label Description
J1 Pull-up for FLT
This jumper is used for pulling up FLT to VOUT.
OPEN : For pulling-up FLT with any other voltage (like VIN), Open this jumper and connect
Pin 2 of J1 externally to the desired voltage (< 60 V).
CLOSED : FLT is pulled-up from VOUT.
J2 UVLO Selection
This jumper is used for selecting UVLO input
1-2: UVLO configured through R2 and R5 resistors. Close Jumper J6 with this configuration.
2-3 : UVLO set to 4-V (POR). Open Jumper J6 with this configuration.
J3 VOUT Indication Close this jumper for powering D4(Green) LED from VOUT
