Input/Output Connector Description

J1 – VBAT is the power input terminal for the converter. The terminal provides power (Vbat).

J2 – GND is the ground terminal for the EVM.

J3 – 5Vg is the power output terminal for the 5Vg regulator output.

J4 – VOUT is the regulated output voltage for the converter.

J5 – GND is a ground terminal for the EVM.

JP1, JP2 – SCR1, SCR0 are jumpers used to set the slew rate of the switching transistor for the L1 terminal switch pin. Jumpers allow the slew rate to be set to four set points.

JP3 – LPM is the jumper used to enable Low Power Mode. The jumper allows LPM to be enabled or disabled. The device will operate in Normal mode when LPM is disabled.
