SLVS927F March 2009 – July 2018 TPS65023-Q1
PRODUCTION DATA.
The TPS65023-Q1 device has 5 regulator channels, 3 DCDCs, and 2 LDOs. DCDC3 has dynamic voltage scaling feature (DVS) that allows for power reduction to CORE supplies during idle operation or overvoltage during heavy-duty operation. With DVS and 2 more DCDCs plus 2 LDOs, the TPS65023-Q1 is ideal for CORE, Memory, IO, and peripheral power for the entire system of a wide range of suitable applications.
The device incorporates enables for the DCDCs and LDOs, I2C for device control, push button, and a reset interface that complete the system and allow the TPS65023-Q1 to be adapted for different kinds of processors or FPGAs.
For noise-sensitive circuits, the DCDCs can be synchronized out of phase from one another, reducing the peak noise at the switching frequency. Each converter can be forced to operate in PWM mode to ensure constant switching frequency across the entire load range. However, for low load efficiency performance the DCDCs automatically enter PSM mode which reduces the switching frequency when the load current is low, saving power at idle operation.
