2.1 Input/Output Connector Descriptions

Reference DesignatorDescription
J1-VINPositive input connection from the input supply for the EVM.
J2-VOUTPositive connection for the output voltage.
J3-GNDReturn connection from the input supply for the EVM.
J4-GNDReturn connection for the output voltage.
J5-VINInput voltage sensing for measuring efficiency. VIN_S+ is for positive input and VIN_S- is for negative input.
J6-VOUTOutput voltage sensing for measuring efficiency. VOUT_S+ is for output positive node and VOUT_S- is for output negative node.
J7-PGTest point to measure PG pin waveform.
JP1-MODEMODE pin input jumper. Place a jumper across MODE and VIN to set the device in forced PWM mode. Place a jumper across MODE and GND to set the device in auto PFM mode.
JP2-ENEN pin input jumper. Place a jumper across EN and VIN to turn on the IC. Place a jumper across EN and GND to turn off the IC.
TP1-SWTest point to measure SW pin waveform.
