Table 2: Jumper Pin Position Assignments
Jumper / Position
Function
VCC/ VBAT
Use this position when powering VBAT and VCC from the same supply. Do not connect power to the
VCC input when using this jumper position.
VCC/ SEP
Use this position when using a separate VCC supply (different from VBAT).
REF/ EXT
Use this position when using an external source to adjust the output voltage.
REF/ INT
Use this position when using the fixed output voltage mode. In this mode the output voltage can be
varied by changing the value of R1 as described in the data sheet.
ADJ/ HF
Use this position when adjusting the output with an external PWM that has a repetition rate in excess of
100KHz.
ADJ/ LF
Use this position when adjusting the output with an external PWM that has a repetition rate less than
100KHz. Or when using a DC adjustment voltage.
VLIM/ IN
Use this position when adjusting the output voltage to prevent the output voltage from accidentally
exceeding 25V.
VLIM/ OUT
This position disables the output voltage adjustment clamp. This position may be desired if maximizing
efficiency when operating near 25V output level.
Note: Always put jumpers in one of the two possible positions
