The TPS65530 is highly integrated 8-channel switching dc/dc converter, and seven channels have integrated power FET.
CH2/4 are configured for H bridge for buck-boost topology and single inductor supports. These channels achieve higher efficiency in spite of input/output voltage conditions.
CH7 has a brightness control and drives white LED by constant current. Also, CH7 supports overvoltage protection for open load.
CH1/2/3 has power ON/OFF sequence suitable for a digital still camera (DSC) system. CH5/6 has a power ON/OFF sequence, depending on the CCD. Power ON/OFF for CCD block (CH5/6) is selectable by the input voltage level at the SEQ56 pin. CH4 and CH7 have individual ON/OFF sequences.
The TPS65530 high switching frequency is achieved by an integrated power MOSFET switch. It reduces external parts dynamically. Shutdown current consumption is less than 1 μA as a typical value.
