Frequently Asked Questions
What is the maximum output current the TPS53313RGER can continuously deliver?
The TPS53313RGER supports up to 6 A of continuous DC output current with integrated power FETs, making it suitable for powering FPGA core rails, DSP cores, and DDR memory supplies at voltages as low as 0.6 V from a 12 V input bus.
Which input voltage range does the TPS53313RGER accept in a 12 V bus system?
The device accepts 4.5 V to 16 V input, covering both the nominal 12 V telecom bus and the 5 V embedded-system bus, and it can handle up to 16 V transients such as those seen during hot-swap events in industrial rack equipment.
How is the output voltage of the TPS53313RGER configured for different rail requirements?
Output voltage is set by an external resistor-divider connected to the feedback pin, adjustable from 0.6 V to 11.2 V, giving designers a single regulator that can produce core voltages (0.9 V, 1.0 V, 1.2 V) and I/O voltages (1.8 V, 2.5 V, 3.3 V) by changing two resistor values.
Does the TPS53313RGER include output power-good signaling for sequenced power-up designs?
Yes, the TPS53313RGER provides a dedicated open-drain power-good output flag that asserts high once the output is within typically 90% of its target voltage, enabling clean power sequencing for multi-rail FPGA and DSP designs that require strict rail-ordering.
At what switching frequency does the TPS53313RGER operate and how does that affect filter component size?
The device operates at up to 1.5 MHz switching frequency, allowing the use of 1 µH to 2.2 µH inductors and 22 µF to 47 µF output capacitors, reducing output filter size by roughly 4x compared to 300 kHz designs and saving significant PCB area.
