Twl6030 Power Companion Ic; Twl6030 Core Smps Outputs - pandaboard OMAP 4 Series System Reference Manual

2.4
The TWL6030 device is a small (7 x 7 mm, 0.4mm pitch) 256 ball FBGA that provides many functions
used on the Platform. Shown below is a feature list of the major functions/interfaces provided by the
TWL6030 device that are utilized on the Panda platform. This list below doesn't include all device
functionality, just that which is used on the PandaBoard.
2.4.1
The TWL6030 implements three Switch Mode Power Supplies (SMPS) that source the three main core
voltage rails for the OMAP4430 processor. The default voltage of all of these supplies is 0.95V, and each
should be adjusted as required by S/W for the desired processor OPP.
VCORE1 is a 1200mA SMPS that is used to power the VDD_MPU balls on the OMAP4430 processor
(net name VDD_VCORE1, 9 balls total). VCORE2 is a 600mA SMPS that is used to power the
VDD_IVA_AUDIO balls on the processor (net name VDD_VCORE2, 10 balls total). VCORE3 is a
600mA SMPS that is used to power the VDD_CORE balls on the processor (net name VDD_VCORE3,
34 balls total) and the VDDA_DLLn_LPDDR21 and VDDA_DLLn_LPDDR22, where n=0 and 1 (4 balls
total).
