2.1 Test Setup

JumperDescription
J1Input voltage positive connection and input voltage return connection.
J2Output voltage positive connection and output voltage return connection.
J3EN pin input jumper. Place a jumper across EN and High to turn on the IC. Place a jumper across EN and Low to turn off the IC.
J4SYNC/MODE pin input jumper. Place a jumper across SYNC/MODE and High to set the device in forced PWM mode. Put the jumper across SYNC/MODE and Low to set the device in auto PFM mode. The jumper can also be removed and the external clock can be synchronized through SYNC/MODE.
J5SSEN pin input jumper. Place a jumper across SSEN and High to enable spread spectrum modulation. Put the jumper across SSEN and Low to disable spread spectrum modulation.
TP1Test point to measure SW pin waveform.
TP2Test point to measure bode plot.
TP3Test point to measure Power-Good indicator voltage.
