Boost (CH5/7)  
Buck (CH1/3)  
The TPS65530A is a fully integrated 8-channel  
switching dc/dc converter, and seven channels have  
integrated power FET.  
Buck-Boost (CH2/4)  
Invert (CH6)  
•
•
•
•
Low-Power Suspend Mode (Sleep Mode)  
Power ON/OFF Sequence (CH1/2/3 and CH5/6)  
LED-Back Light Brightness Control (CH7)  
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.  
Fixed Switching Frequency (CH1–4: 1.5 MHz,  
CH5–8: 750 kHz)  
CH7 has a brightness control and drives white LED  
by constant current. Also, CH7 supports overvoltage  
protection (OVP) for open load.  
•
•
•
•
Fixed Max Duty Cycle Internally  
Soft Start  
CH1/2/3 have a power ON/OFF sequence suitable for  
a digital still camera (DSC) system. CH5/6 have 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.  
Undervoltage Lockout (UVLO)  
Protection  
–
–
–
Thermal Shutdown (TSD)  
Overvoltage Protection (OVP)  
Overcurrent Protection (OCP) Except CH8  
The TPS65530A 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.
