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. Connect the jumper between EN and the High pin 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 bode High to set the device in forced PWM mode. Connect the jumper between 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. Connect the jumper between SSEN and Low to disable spread spectrum modulation.
TP1Test point to measure SW pin waveform
TP2Test point for bode plot measurement
TP3Test point to measure power-good indicator voltage
