    2.4.2 TWL6030 V1V8 SMPS Output The TWL6030 V1V8 SMPS provides the I/O voltage for the PandaBoard (net name VIO_1v8). This is a 1200mA SMPS that provides a 1.8V output that is used to power many balls on the OMAP4430 processor that set the I/O voltage for the device. It also sources onboard peripherals that require an operating voltage referenced to processor I/Os.

    USB transceiver. The only ball powered by this LDO is the VDDA_USBA0OTG_3P3V ball (ball A5). The VPP LDO is adjustable LDO that powers the VPP_CUST and VPP_STD balls on OMAP (balls J8 and Y22). This LDO is only needed for eFuse operations and can be left disabled for normal PandaBoard operation. 2.4.7 TWL6030 Clock Circuitry The TWL6030 has an 32.768 KHz crystal connected across its OSC32KIN and OSC32KOUT balls.
