Frequently Asked Questions
What is D-CAP2 control topology?
D-CAP2 is TI's adaptive on-time control that eliminates the need for external compensation components. It provides extremely fast transient response (within 1-2 clock cycles) by directly sensing output voltage ripple, ideal for processors with rapid load steps.
What current can TPS53318 deliver?
The TPS53318 integrates gate drivers and is designed to drive external power MOSFETs for currents up to 30A+ depending on MOSFET selection. For the complete power stage, it pairs with CSD87350Q5D or similar NexFET power stages.
What output voltages does TPS53318 support?
Output voltage is adjustable from 0.6V to VIN via resistor divider. Common configurations include 0.9V/1.0V/1.2V/1.5V/1.8V/3.3V for processor core, memory, and I/O voltages. Remote sense pins ensure accurate voltage at the load.
Is TPS53318 suitable for DDR memory power?
Yes, the TPS53318 can regulate DDR3/DDR4 memory voltages (1.2V-1.5V) with the fast transient response needed for DRAM traffic patterns. The D-CAP2 topology handles the rapid load changes characteristic of memory controller access patterns.
