2.1 Input/Output Connector Descriptions

See the following:

TP1Positive connection of the power supply
TP2Positive connection for the load
TP3Negative connection of the power supply
TP4Negative connection for the load
TP5Test point to measure the Bode plot
TP6Test point to measure SW pin waveform
J1Input voltage sensing for measuring efficiency. VIN_S+ is for positive input and VIN_S- is for negative input.
J2Output voltage sensing for measuring efficiency. VOUT_S+ is for output positive node and VOUT_S- is for output negative node.
J3MODE pin input jumper. Place a jumper across MODE and VCC to set in forced PWM mode, place a jumper across MODE and GND to set in auto PFM mode.
J4EN pin input jumper. Place a jumper across EN and ON to turn on the IC. Place a jumper across EN and OFF to turn off the IC.
J5Fixed output voltage selection jumper. Solder a 0 Ω at R14. Place a jumper across pin 1 and pin2 to set 5-V fixed Vout, place a jumper across pin 3 and pin 4 to set 5.25-V fixed Vout, place a jumper across pin 5 and pin 6 to set 5.5-V fixed Vout.
