ORDERING INFORMATION
–
Buck (CH1/3)
The
TPS65530
is
a
fully
integrated
8-channel
–
Buck-Boost (CH2/4)
switching dc/dc converter, and seven channels have
–
Invert (CH6)
integrated power FET.
Low-Power Suspend Mode (Sleep Mode)
CH2/4 are configured for H bridge for buck-boost
Power ON/OFF Sequence (CH1/2/3 and CH5/6)
topology
and
single
inductor
supports.
These
LED-Back Light Brightness Control (CH7)
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
Fixed Max Duty Cycle Internally
protection (OVP) for open load.
Soft Start
CH1/2/3 have a power ON/OFF sequence suitable for
Undervoltage Lockout (UVLO)
a digital still camera (DSC) system. CH5/6 have a
Protection
power ON/OFF sequence, depending on the CCD.
–
Thermal Shutdown (TSD)
Power ON/OFF for CCD block (CH5/6) is selectable
by the input voltage level at the SEQ56 pin. CH4 and
–
Overvoltage Protection (OVP)
CH7 have individual ON/OFF sequences.
–
Overcurrent Protection (OCP) Except CH8
The TPS65530 high switching frequency is achieved
Supply Voltage Range: 1.5 V to 5.5 V
by an integrated power MOSFET switch. It reduces
Operating Temperature Range: –25°C to 85°C
