Jumper Settings

Jumpers Description
JP1 VPWI selection, default VPWI = 2.5 V
JP2 AVIN selection, default AVIN = PVIN
J2 Default Closed: switching frequency is controlled by R20 (300 kHz default)
When Open: switching frequency is synchronized to clock source connected to SYNC terminal
J3 Default OPEN
Should only be connected when AVIN ≤ 5 V. When AVIN ≤ 5 V, connecting J3 can improve efficiency.
Caution: if AVIN > 5.5 V, connecting J3 could damage the LM10500 device.
J7 Default OPEN
Should only be connected when no voltage supply is connected to PVIN and AVIN. Intended for easy demonstration of the board by powering PVIN and AVIN by VBAT = 3.6 V.
Caution: if PVIN is higher than 5.5 V, connecting J7 could damage the USB2PWI board. VBAT can not support large load current.
P1 PWI version and address selection. Note that the LM10500 supports PWI1, PWI2-0, PWI2-1, PWI2-2, and PWI2-3. The USB2PWI board supports PWI1 and PWI2-0.
