The TPS68470 device is an advanced power management unit that powers a Compact Camera
Module (CCM), generates the clock for the image sensor, drives a dual LED for Flash and
incorporates two LED drivers for general purpose indicators . The TPS68470 is capable of generating
all needed power rails in a CCM.
The CORE voltage regulator is a state of the art buck converter which can be used for the
image sensor digital supply. An LDO (LDO_ANA) can be used for the image sensor analog supply.
The TPS68470 also has a high efficiency boost converter to support two 1A LED flash
drivers. The LED currents are controlled with regulated low side current sources.
The TPS68470 has five other LDOs. Two of them can be used for generic and sensor IO
supply voltage generation (LDO_IO and LDO_S_IO). One can be dedicated to the VCM driver supply
(LDO_VCM). The remaining two are auxiliary LDOs (LDO_AUX1 and LDO_AUX2).
